(-8, -1) slope = -3/4
babunello [35]

Answer:

y=-3/4x - 7

Step-by-step explanation:

When finding the slope given a point and a slope, we do the following.

y=mx+b  (Slope-intercept Form)

m is the slope and x,y are the points

Plug in everything

-1= -3/4(-8)+b

Multiply

-1 = 6 + b

-7 = b

This gives us the final equation of y=-3/4x - 7

A line goes through the points (-2, 4) and (0, -1).
jarptica [38.1K]
Here you go! I worked it out for the easiest way to find slope and both possible points being used for the point-slope form. The image also forgot to include slope intercept is y=mx+b where m is slope and b is y- intercept. Hope this helps.
