Answer:

Step-by-step explanation:

Slope of line that passes through two points: $m=\dfrac{y_2-y_1}{x_2-x_1}$

(2, -8) ⇒ x₁ = 2, y₁ = -8

(3, 1) ⇒ x₂ = 3, y₂ = 1

$\bold{m=\dfrac{1-(-8)}{2-2}=\dfrac{1+8}1=9}$

Lisa [10]

Answer:

y = 0

Step-by-step explanation:

Plug in 28 for x. Solve for the equation:

x + 3y = 28

(28) + 3y = 28

Isolate the variable, y. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS. First, subtract 28 from both sides:

28 (-28) + 3y = 28 (-28)

3y = 0

Isolate the variable, y. Divide 3 from both sides:

(3y)/3 = (0)/3

y = 0

y = 0 is your answer.

First distribute the 2, then add 7 to that side, so you have 2g+17=-4g+g , subtract 2g and it should be easy to find from there lol
