The answer is a.
Substitute (-2,1) and (1,10) into each answer. Only a is correct because you will get -7 from both points.

What is the slope of the line that passes through (-2,7) and (4, 9)? Type a numerical answer in the space provided. If
lord [1]

Answer:

1/3

Step-by-step explanation:

You need to use slope formula. (the change in Y over the change in X = Slope [x1-x2/y1-y2 = slope]). I believe you can also use point slope formula, but I forgot how to do that one.

First, you would set up the equation.

7-9/-2-4 OR 9-7/4+2

you would then solve to get

-2/-6 OR 2/6

when simplified you get

1/3

for both. Hope it helps!
