Question

graph for 2x-5y=20

Answer 1

2 ways to do this:
1. solve for y and you get a slope-intercept form...then graph it.
2. Plug 0 in for x and solve for y..gives you a point(0,y)
Plug 0 in for y and solve for x..gives you a point(x,0)...then plot the 2 points and connect with a line

Answer 2

That equaion is in standard form so you have to covert it in slope intercept
