Then, use either point to get the equation. y-y1 = m*(x-x1) (x1,y1) is the point. y-20 = 3*(x-5) y-20 = 3x-15 y = 3x + 5 The y-intercept is 5, at (0,5). -------------------------- Then you can make one more point, and since it's a straight line, draw the line thru them. Give x any value, and find y. eg, x = 3, y = 14 --> (3,14)
