$y=8.50x$

#### Work Step by Step

Let x be the number of lawns and let y be the amount earned. "\$8.50 each" tells us to multiply the number of lawns mowed by \$8.50 to find the amount earned. $y=8.50x$ Create a table with some values that satisfy the equation. $\underline{lawns\ mowed,\ x}\ \ \ \underline{amt\ earned,\ y}$ $\ \ \ \ \ \ \ \ \ \ 1\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \$8.50\ \ \ \ \ \ \ \ \ \ 2\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \$17.00$ $\ \ \ \ \ \ \ \ \ \ 3\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \$25.50\$ Plot the points in the table. Plot additional points on the imaginary line connecting the points. Only plot points for whole number values of x since only whole lawns are mowed.
