for point(-2,2)
y%5B1%5D+=+2
x%5B1%5D+=+-2
for point(3,7)
y%5B2%5D+=+7
x%5B2%5D+=+3
%28y+-+2%29+%2F+%28x+-+%28-2%29%29+=+%287+-+2%29+%2F+%283+-+%28-2%29%29
%28y+-+2%29+%2F+%28x+%2B+2%29+=+5+%2F+5
5%28y+-+2%29+=+5%28x+%2B+2%29
y+-+2+=+x+%2B+2
y+=+x+%2B+4 answer
m = 1
b = 4
check this- does it go throught points (-2,2) and (3,7)?
2+=+-2+%2B+4
2+=+2
7+=+3+%2B+4
7+=+7
OK
