12 = 3x - 15
12 + 15 = 3x
27 = 3x
27/3 = x
9 = x
x = 9

Answer:
2/5
Step-by-step explanation:
Let's simplify this equation to find the slope. I am going to make this into
y = mx+b form where m is the slope and b is the y-intercept.
y - 3 = 2/5(x+7)
y - 3 = 2/5(x) + 14/5
y = 2/5(x) + (14/5 + 3)
y = 2/5(x) + 29/15
The slope of this equation is 2/5
