Solving an Slope Intercept equation
Homework: Due Friday, Nov. 23. On you blog solve the point-slope equation above (slope = -2 & the X1,Y1 point is 8,4)
(y-4)=-2(x-8)
+4 +4
Y=-2 (x-4)
Y= x-2
Your post should actually read converting point-slope form to slope-intercept form.
To prevent any confusion, you should distribute the multiplication first -2(x-8) so you get -2x + 16. Then you get y-4 = -2x + 16 Adding 4 to each side you get y = -2x + 20
