Question

identify an equation in slope intercept form for the line parellel to y=-3x+7 that passes through (2,-4)

Answer 1

y= -3x+2

Explanation:

Parallel lines have the same slope. We can form an incomplete equation:

y= -3x+b

(make sure to see why the slope is -3)

We can plug in the coordinates of (2, -4):

-4= -3(2)+b

-4= -6+b

2=b

b is 2! We can form an equation: y= -3x+2
