Question

graph 4x+5y=-20

Answer 1

put into slope intercept form y=mx+b
5y=-4x-20 isolate y by dividing everything by 5
y=-4/5x-4
the -4 is your y-intercept
-4/5 is your slope, (rise/run) from your y-intercept go down four, to the left 5 then from your y-intercept go up 4 and to the right 5 and you should be able to sketch a line like i have shown
