Question 295354
Quickest way is to find the intercepts and plot them.
To find the x-intercept, set y=0 and solve for x.
{{{2x-5y=-10}}}
{{{2x=-10}}}
{{{x=-5}}}
(-5,0)
To find the y-intercept, set x=0 and solve for y.
{{{2x-5y=-10}}}
{{{-5y=-10}}}
{{{y=2}}}
(0,2)
.
.
Plot those two points. 
Then connect them with a line.
