Question 13 options:<br><br><br> What is the slope of the line of the graph?
Elena-2011 [213]

Answer:

Step-by-step explanation:

To find the slope, pick any two points fromthe line.

(2,2)  & (0,-4)

x₁ = 2 & y₁ = 2

x₂ = 0 & y₂ = - 4

\boxed{Slope=\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}}

          \sf =\dfrac{-4-2}{0-2}\\\\\\ =\dfrac{-6}{-2}\\\\\\=3

Slope = 3

At y-intercept x = 0.

From the graph, y-intercept = -4

Equation of the line: y = mx + b

y = 3x - 4
