I have no idea what the answer is to this question
So y=mx+b
m=slope
y=-3x+b
subsitutue 1 for x and 4 for y
4=-3(1)+b
4=-3+b
add 3 to both sides
7=b
the equaiton is y=-3x+7
<em>x = 8</em>
Step-by-step explanation:

Add 1 to both sides.

Add 2x to both sides.

Divide 40 by 5.
x = 8
May I ask what is the given location of M?
