Answer
Refer to the graph below.
Work Step by Step
The given equation can be graphed using its intercepts.
Find the x-intercept by setting $y=0$ then solving for $x$:
$2x+5y=20
\\2x+5(0)=20
\\2x=20
\\\frac{2x}{2}=\frac{20}{2}
\\x=10$
The x-intercept is $(10, 0)$.
Find the y-intercept by setting $x=0$ then solving for $y$:
$2x+5y=20
\\2(0)+5y=20
\\5y=20
\\\frac{5y}{5}=\frac{20}{5}
\\y=4$
The y-intercept is $(0, 2)$.
Plot the x and y-intercepts then connect them using a straight line.
(Refer to the graph in the answer part above.)
