It’s b I had it in my test
Answer:
Anyone have all the answers?
Step-by-step explanation:
We know from the slope intercept form that y=mx+b so the y intercept is 12 while every hour the cost goes up by 8
Point-slope form: y - y₁ = m(x - x₁)
(m is the slope, (x₁, y₁) is the point you are given that is on the line)
You know:
m = 5
(x₁, y₁) = (-2, -3) So substitute/plug it into the equation
y - y₁ = m(x - x₁)
y - (-3) = 5(x - (-2)) (two negative signs cancel each other out and become positive)
y + 3 = 5(x + 2) Your answer is A
