Answer:
y= -1/3+ 5.3
Step-by-step explanation:
You take any two sets of points and do the formula [tex]\frac{Y2-Y1}{X2-X1}[/tex]
I chose ( -1,-5) as X1 and Y1 and (-5,7) as X2 and Y2.
Plug that into the formula and you should get [tex]\frac{-1}{3}[/tex]. That is your slope.
To find y intercept we use the formula [tex]y= mx + b[/tex].
We know our slope which is m, and to find y-intercept we use any point that was given to use in place of x and y in the formula. I used (-5,7).
Which looks like [tex]7= \frac{-1}{3}(-5) + b[/tex].
After solving for b you should get 5.3
Final answer should be y= -1/3+ 5.3
