Question

What is the slope of the line?
y +3 = -4(x+7)

Answer 1

-4

Explanation:

We need to go over point-slope form:

y - y1 = m(x - x1)

In this equation m represents the slope

So, let's convert:

y +3 = -4(x+7)

m being -4, so the slope of the line is -4.

Answer 2

-4

Explanation:

Compare this to the form ...

y -y1 = m(x -x1)

which is the point-slope form of the equation for a line. Matching the parts of the equation, you see that ...

• y1 = -3
• m = -4
• x1 = -7

m represents the slope of the line. The slope is -4.
