You can put this solution on YOUR website!
Y=mX+b
5=(-2*-1)+b
5=2+b
b=5-2
b=3 THEN THE EQUATION IS
Y=-2X+3

point-slope formula
m+=+%28y+-+y%5B1%5D%29+%2F+%28x+-+x%5B1%5D%29
where m = slope, (x[1], y[1]) is the given point, (-1,5)
-2+=+%28y+-+5%29+%2F+%28x+-+%28-1%29%29
multiply both sides by %28x+-+%28-1%29%29
-2x+-2+=+y+-+5
add 5 to both sides and rearrange
y+=+-2x+%2B+3 answer
