Question 562342
I think you meant:
y=-3x+12
.
If so, the slope of the line above is -3
If the new line is parallel, it must have the same slope.
.
Plug the slope (-3) and the given point (-1,6) into the "point-slope" form:
y - y1 = m(x - x1)
y - 6 = -3(x - (-1))
y - 6 = -3(x + 1)
y - 6 = -3x - 3
y = -3x + 3 (this is what they're looking for)
