Question 235425: determine the slop and y intercept (4,8)(-3,-4)
y=mx+b
Answer by checkley77(12844) (Show Source): You can put this solution on YOUR website!
Slope=(y2-y1)/(x2-x1)=(-4-8)/(-3-4)=-12/-7=12/7
8=12/7*4+b
8=48/7+b
b=8-48/7
b=56/7-48/7
b=8/7 the y intercept.
y=12x/7+8/7
(graph 300x200 pixels, x from -6 to 5, y from -10 to 10, 12x/7 +8/7).
