Answer:

a

Explanation:

it has to have to same slope as the first equation so you have y=5x+b then what you do is plug in the points and solve for b. which gives you 2. so your final equation is y=5x+2

7=5+b

-5 -5

2=b

Answer:

The equation that represents the line that passes through (1,7) and is parallel to y = 5x + 4 will be:


  • y=5x+2

Explanation:

Given the equation


y = 5x + 4

Here the slope is:


m=5

as comparing with the
y=mx+b, which is the slop-intercept form where m is the slope and b is the y-intercept.

As we know the point-slope form is


y-y_1=m\:\left(x-x_1\right)


y-7=5\left(x-1\right)

Add 7 to both sides


y-7+7=5\left(x-1\right)+7


y=5x+2

Therefore, the equation that represents the line that passes through (1,7) and is parallel to y = 5x + 4 will be:


  • y=5x+2
