You can put this solution on YOUR website!
you will find the x and y intercept of 4x=7y%2B9 if you set x=0 and solve for y, then set y=0 and solve for x
if x=0
4%2A0=7y%2B9
0=7y%2B9
-9=7y
-9%2F7=y
or
-1.29=y.....so, the y intercept is at (0,-1.29)

if y=0
4x=7%2A0%2B9
4x=0%2B9
4x=9
x=9%2F4
or
x=2.25.......and the x intercept is at (2.25,0)

let's check it on a graph
