#2.
a) 1/4m + 3 = 2
1/4m = -1
m = -4
b) 4y - 3(y + 8) = 12
4y - 3y + 24 = 12
y = -12
For #10, letter b. Do the same thing you did with letter a.
The equation is already given.
You have your y-intercept: -8, and your slope: 3/1.
These two create two different points you can add to your data table.
(0, -8) and (1, 3)
y:-8, 3
x: 0, 1
