how can I look a line and find the y intercept form if I can't read the y intercept directly from the graph? Two points on exact grid lines: (7, 6) (4, 0)

You can find the slope-intercept form y = mx + b from two points.

1. Compute the slope m = (y2 − y1)/(x2 − x1) = (6 − 0)/(7 − 4) = 6/3 = 2.
2. Use one point to solve for b. Using (4,0): 0 = 2(4) + b → b = −8.

So the equation is y = 2x − 8, with y-intercept (0, −8).
