What is an equation of the line that passes through the point (5, 4) and is parallel to
the line 6x – 5y = 15?
Someone please help me
Answer & Step-by-step explanation:
When two lines are parallel, their slopes are the same. To find the slope of the given equation, convert to slope-intercept form:
[tex]y=mx+b\\\\[/tex]
m is the slopeb is the y-intercept, which is the value of y when the value of x is zerox and y are the corresponding coordinate points (x,y)[tex]6x-5y=15[/tex]
Solve for y. Subtract 6x from both sides:
[tex]6x-6x-5y=15-6x\\\\-5y=-6x+15[/tex]
Divide both sides by -5:
[tex]\frac{-5y}{-5} =\frac{-6x}{-5} +\frac{15}{-5} \\\\y=\frac{6}{5}x-3[/tex]
The slope is [tex]\frac{6}{5}[/tex].
Now you need to make an equation in point-slope form:
[tex]y-y_{1}=m(x-x_{1})[/tex]
m is the slope[tex]x_{1}[/tex] and [tex]y_{1}[/tex] are the coordinate pointsInsert known values:
[tex]y-4=\frac{6}{5}(x-5)[/tex]
You can use this equation, or you can convert to slope-intercept form by solving for y:
Use the distributive property:
[tex]y-4=\frac{6}{5} x-6[/tex]
Add 4 to both sides:
[tex]y-4+4=\frac{6}{5}x-6+4\\\\ y=\frac{6}{5}x-2[/tex]
:Done
The equation of the perpendicular line is [tex]y = \frac 65x - 2[/tex]
The equation of the line is given as:
[tex]6x -5y = 15[/tex]
Start by calculating the slope (m) of the line as follows:
[tex]6x -5y = 15[/tex]
Subtract 6x from both sides
[tex]-5y = 15 - 6x[/tex]
Divide both sides of the equations by -5
[tex]y = -3 + \frac65x[/tex]
Rewrite as:
[tex]y = \frac65x-3[/tex]
For a linear equation, y = mx + b, the slope of the line is m
So, the slope is:
[tex]m = \frac65[/tex]
The equation of the line is said to be parallel to the above equation
So, the slope of the line is:
[tex]m = \frac65[/tex]
The line is said to pass through point (5,4).
So, the equation of the line is:
[tex]y = m(x - x_1) +y_1[/tex]
This gives
[tex]y = \frac 65(x - 5) +4[/tex]
Expand
[tex]y = \frac 65x - 6 +4[/tex]
[tex]y = \frac 65x - 2[/tex]
Hence, the equation of the line is [tex]y = \frac 65x - 2[/tex]

Sharon is planning a holiday for 4 people for 7 days
Here are the costs for the holiday for each person
Travel-£130 hotel-£60 for each day spending money-£350
Work out the total cost of the holiday for 4 people for 7 days
Answer:
3600
Step-by-step explanation:
Each PERSON cost:
Travel cost 130 (assume for whole 7 days since per day is not written)
Hotel 60 per day (so 7 days = 60 * 7 = 420)
Money Spend 350 (assume for whole 7 days since per day is not written)
-------------------------------------------------------------------------------------------------------------
Now, that sums to:
130 + 420 + 350 = £900 [each person for whole 7 days]
Now, there are 4 person, so total cost of whole group (4 persons):
900 * 4 = £ 3600

A line that passes through the point (x,y), with a y-intercept of b and a slope of m, can be represented by the equation y = mx + b.
A line is drawn on the coordinate plane that passes through the point (10,1) and has a slope of -0.5. The y-intercept of the line is.
HELP!!!!
The equation of a line passes through the point (10,1) and has a slope of
- 0.5 is y = - 0.5x + b.
What is slope?The slope is the rate of change of the y-axis with respect to the x-axis.
The equation of a line in slope-intercept form is y = mx + b, where
slope = m and y-intercept = b.
We know the greater the absolute value of a slope is the more steeper is its graph or rate of change is large.
Yes, A line that passes through the point (x, y), with a y-intercept of b and a slope of m, can be represented by the equation y = mx + b.
Now, A line is drawn on the coordinate plane that passes through the point (10, 1) and has a slope of - 0.5.
Therefore, 1 = - 0.5(10) + b.
1 = - 5 + b.
b = 6.
And hence equation of the required line is,
y = - 0.5x + 6.

*** hey can someone explain to me how to solve this question, thank youu
Answer: One way to find the least common multiple of two numbers is to first list the prime factors of each number. Then multiply each factor the greatest number of times it occurs in either number. If the same factor occurs more than once in both numbers, you multiply the factor the greatest number of times it occurs.

The graph shows the relationship between the United States dollar and the euro, the currency of the European Union, in December 2011. Part A: What is the constant of proportionality shown in the graph?
Answer:
The constant of proportionality is 3/4
Step-by-step explanation:
Here, we want to write the constant of proportionality in the given graph .
To find the constant of proportionality, we need to find the slope of the line.
We can get the slope by using two of the points on the line.
Mathematically, slope of a line m is;
m = (y2-y1)/(x2-x1)
Let (x1,y1) = (120,90) and (x2,y2) = (400,300)
slope will be ( 300-90)/(400-120) = 210/280 = 3/4
