Respuesta :
Find the slope between these 2 points and then plug the coordinates and the slope into point intercept
If you use:
Y1-Y2/X1-X2, you will get
-9-5/7-3 which equals -3.5.
Then you would use y=mx+b and plug in the slope into 'm'
y=-3.5x+b
And in order to find 'b' you would want to plug in one of the corrdinates
-9=-10.5+b
And solve the equation:
b=1.5
So the answer is:
y=-3.5x+1.5
