Question 26370
15First you need to put the equation in slope-intercept form;
y=mx+b
4x+5y=15
5y=15-4x
5y=-4x+15
y=-{{{4/5}}}x+15
So now y-intercept = 15, and slope is -{{{4/5}}}
So on the graph you will plot the point (0,15), and from there and with the slope of -{{{4/5}}}, you will plot your next point. 
From point (0,15) you will go down 4 units and to the left 5.
When you have 3 points you connect those with a line.
{{{graph (600,300, -10,3,-3,20, (4/5)x+15)}}}
Hope you understand
