Answer

(-20, 0), (0, 8/3)

Work Step by Step

$\frac{2x}{5} + 8 - 3y = 0$ Set y=0 and solve for x to find the x-intercept. $\frac{2x}{5} + 8 - 3(0) = 0$ $\frac{2x}{5} = -8$ x = -5/2*8 = -20 (x-intercept) Set x=0 and solve for y to find the y-intercept. $\frac{2(0)}{5} + 8 - 3y = 0$ 8 = 3y y=8/3 (y-intercept)
