-2x%2B5y=15 here, you have a linear equation (or function), its graph is a line and you need two points that lie on line in order to graph it
easiest way is to find x and y-intercept
set x=0 and find y-intercept
-2%2A0%2B5y=15
5y=15
y=15%2F5
y=3
so, y-intercept is at (0,3)

set y=0 and find x-intercept
-2x%2B5%2A0=15
-2x=15
x=15%2F-2
x=-7.5
so, x-intercept is at (-7.5,0)
now plot these points and draw a line through
