x - intercept:
(, ) o absent
y - intercept:
Step1: Find x-intercept (set y=0)
Set $y=0$ in $5x + 8y = -20$:
$5x + 8(0) = -20$
$5x = -20$
$x = \frac{-20}{5} = -4$
x-intercept is $(-4, 0)$
Step2: Find y-intercept (set x=0)
Set $x=0$ in $5x + 8y = -20$:
$5(0) + 8y = -20$
$8y = -20$
$y = \frac{-20}{8} = -\frac{5}{2}$
y-intercept is $(0, -\frac{5}{2})$
