SOLUTION: Hi I'm supposed to put this into slope-intercept form. (10,-3) (-8,-9) Would I use m= y2-y1 over x2-x1 to get the slope? Then do I need to use the point-slope formula y-y1=m(

Question 272115: Hi
I'm supposed to put this into slope-intercept form. (10,-3) (-8,-9)
Would I use m= y2-y1 over x2-x1 to get the slope? Then do I need to use the point-slope formula y-y1=m(x-x1)? I'm not sure if I'm ending up with the right answer. y=1/3x-19/3
Thanks
Rachel

Given points are A(10,-3) and B(-8,-9)
The equation of the line through A and B is
(x-x1)/(x2-x1) = (y-y1)/(y2-y1)
(x-10)\(-8-10)= (y+3)/(-9+3)
-6(x-10) = -18(y+3)
x-10=3(y+3)
x-10=3y+9
x-10-9=3y
y=(1/3)x-19/3
