Question

What is the slope of a line that passes through the point (−2, 3) and is parallel to a line that passes through (3, 7) and (−2, −8)?

Answer 1

If it is parallel, it has the same slope

Answer 2

m=(-8-7)/(-2-3)
y=mx+b
plug in (-2,3) in equation after you get slope to solve for b.

Answer 3

\[m=\frac{ y2-y1 }{ x2-x1 }\]

Answer 4

wait so i just find the slope of (-8-7) and (-2-3) ?

Answer 5

yeah you divide change in y over change in x to get slope

Answer 6

And parallel lines have same slope

Answer 7

4/6?

Answer 8

Example of parallel lines, same slope

Answer 9

4/6?

Answer 10

\[\frac{ -8-7 }{ -2-3 }=\frac{ 15 }{ 5 }=3\]

Answer 11

wouldnt it be -15/-5?

Answer 12

it simplifies down to 3.

Answer 13

so m=3 ?

Answer 14

yes

Answer 15

oh okay ..thanks :)

Answer 16

A negative number multiplied by a negative numer is positive
