Question 1013235: Use the given conditions to write an equations for the line in point-slope form andslope intercept form
Passing through (-4,9) and (1,-1)
What is the equation of theline in point slope form?
What is the equation of the line in slope intercept form?
I got y=-2x+1 for both. I don't think this is correct though

You can put this solution on YOUR website!
slope m = (-1 -9) / (1 - (-4)) = -2
y = -2x + b
-1 = -2 + b
b = 1
y = -2x + 1, therefore
***************************************
point slope form is
(y-(-1)) = -2(x-1)
y+1 = -2(x-1)
**************************************
slope intercept form
y = -2x + 1
