What is the slope of the line that passes through the points (1, 7) and (–4, –8)?

A.
–3

B.
-1/3

C.
1/3

D.
3

Answer 1

\[\frac{ y1-y2 }{ x1-x2 } = \frac{ 7-(-8) }{ 1-(-4) } = \frac{ 15 }{ 5 } = 3\] So the answer is D.

Answer 2

thanks

Answer 3

\[\frac{ y2-y1 }{ x2-x1 }=\frac{ -8-7 }{ -4-1 }=\frac{ -15 }{ -5 }=3\]
Sorry this is what I meant. You still get the same answer.
