Answer:
r = -1
Step-by-step explanation:
To get r isolated, you have to divide each side by -7
7 divided by -7 is -1, therefore r = -1
Answer:
y= 1.5x
Step-by-step explanation:
The y-intercept is 0 so we don't put anything there. The slope is 1.5. You can find the slope by using rise and run.
Answer:
He has 4 10/12 wire left
Step-by-step explanation:
Answer:
y + 16 = 3(x + 5)
Step-by-step explanation:
When you write an equation in point-slope form, you only need two things: a point and a slope.
Given:
The standard point-slope equation is
y - y₁ = m(x - x₁)
Plug in what you know.
y - (-16) = 3(x - (-5))
Simplify.
y + 16 = 3(x + 5)
This is your equation.
