Question 282003
Always easier to convert into slope-intercept form (y=mx+b).

{{{2x+5y=10}}} now, subtract 2x from both sides

{{{5y=-2x+10}}} next, divide both sides by 5, to isolate y

{{{y=-(2/5)x+10}}} now graph, slope of -2/5, y-intercept at 10

{{{graph(200, 200, -12, 12, -12, 12, -.4x+10)}}}
