Question

Choose the equation below that represents the line passing through the point (-3, -1) with a slope of 4.

y = 4x - 11

y = 4x + 11

y = 4x + 7

y = 4x - 7

Answer 1

Use the point slope formula:

\[m=4\]
\[x _{0} = -3\]
\[y _{0}= -1\]
\[y-y _{0}=m(x-x _{0})\]

Answer 2

So:

y - (-1) = 4 (x - (-3))
y + 1 = 4x + 12
y = 4x + 11
