You need to simplify it first.

Use distribution

y=mx+b
m=slope
your slope is -4 :)
Answer: slope is 0
to find the slope , you have to subtract y-es and divide them by x-es.(delta y/ delta x)
so,
(-6,-2) (-7,-2)
slope: -2-(-2)/-7-(-6)
slope:0/ -1
slope: 0
which looks on the graph like this:
4x - 3 = 9
4x = 9 + 3
4x = 12
x = 3
hope that helps, God bless!
Answer:
a) 22.8%
Step-by-step explanation:
