You can put this solution on YOUR website!
The given points are (4,0) and (0, 9)
The slope is (change in y)/(change in x)
slope = %289+-+0%29+%2F+%280+-+4%29+=+-9%2F4
In the form y+=+mx+%2B+b, m is the slope
and b is the y-intercept, so the equation is
y+=+-%289%2F4%29%2Ax+%2B+9
To check the answer, plug in (4,0) and (0,9)
first,
0+=+-%289%2F4%29%2A4+%2B+9
0+=+-9+%2B+9
0+=+0
OK, and
9+=+-%289%2F4%29%2A0+%2B+9
9+=+9
OK
