Question

What is the answer to number 39

Answer 1

Parallel lines have the same a slope.

The slope-intercept form:

`y=mx+b`

m - slope

b - y-intercept

We have y = -2x - 6 → the slope m = -2. Therefore we have the equation of a line:

`y = -2x + b`

Put the coordinates of the point (-4, 1) to the equation:

`1=-2(-4)+b`

`1=8+b` subtract 8 from both sides

`-7=b\to b=-7`

Answer: y = -2x - 7
