gin—=11: ' Since the third point is on the line, the
graph shown on the right is correct. "1e yintercept is the point at which the
graph crosses the yeaxis. The graph of an
equation in the form y=n1x+ 13 passes
1rough the yintercept (0,13). Since the equation is in the form
y=rnx+ b, the yeintercept can be read
irectly from the equation *l "he yintercept is (D,  9). Question is complete. ...
