Write an equation for the line that is parallel to y=-4x+2 and goes through (0,7)
Soloha48 [4]

Answer:

The answer is

<h2>y = - 4x + 7</h2>

Step-by-step explanation:

Equation of a line is y = mx + c

where

m is the slope

c is the y intercept

To find the equation of the parallel line we must first find the slope of the original line

The original line is y = - 4x + 2

Comparing with the general equation above

Slope / m = - 4

Since the lines are parallel their slope are also the same

Slope of parallel line = - 4

So the equation of the line using point (0,7) and slope - 4 is

y - 7 =  - 4(x - 0) \\ y - 7 =  - 4x

We have the final answer as

<h3>y = - 4x + 7</h3>

Hope this helps you

What is the value of x in the equation 3x-4y=65, when y=4?<br> WN
Naya [18.7K]

Answer:

x=27

Step-by-step explanation:

3x -4y =65

Let y=4

3x -4*4 =65

3x-16 = 65

Add 16 to each side

3x-16+16 = 65+16

3x = 81

Divide each side by 3

3x/3 = 81/3

x = 27
