Question

Q1)Write the equation form y=mx+b using this information: (1,-1) is on the line and the slope is -6.

Q2)Write the equation form y=mx+b using this information: (-5,-2) is on the line and the slope is -1.

Answer 1

1) since slope is -6, we have y=-6x+b
Plugging in (1,-1), we get -1=-6*1+b
b=5
y=-6x+5
2) since slope is -1, we have y=-x+b
Plugging in (-5,-2), we get -2=-1*-5+b
b=-7
y=-x-7
