Question 902522: Suppose a line goes through the points (3,1) and (-2,-9). Write the equation of the line. Determine the intercepts of the line and sketch the graph.
(I solved everything and graphed the equation, but when I check my solution it doesn't check out. I just need help checking my solution)

You can put this solution on YOUR website!
y=mx+b and b=y-mx

m=%281-%28-9%29%29%2F%283-%28-2%29%29=10%2F5=2

Using (3,1):
b=1-2%2A3=-5

EQUATION: highlight%28y=2x-5%29
