As shown in the figure, the straight line Y is equal to kx plus 6, and the X-axis of the Y-axis intersects with the point efa-80A and subtracts 60 to find the value of K. If the point pxy is straight,

1 y=kx+6

Replacement point e (-8,0)

0=6-8k k=3/4

y=3x/4+6

2 OPA area = |-6 | | | 3x/4+6 |/2 = | 9x/4+ 18 |

Because the points P∈, 9x/4+18 >; =0

Sopa=9x/4+ 18 -8
