i dont understand this problem it says:
write an equation that has a slope of -3 and passes through the point (-6,9)
---------------------
The form of the equation is y = mx + b
You are told that m = -3 and that y = 9 when x = -6.
So, solve for "b".
9 = -3*-6 + b
9 = 18 + b
b = -9
---------
Equation:
y = -3x -9

y=mx+b
y=-3x-9
