What is the slope of the line on the graph?
Minchanka [31]

Answer:

slope = \frac{1}{2}

Step-by-step explanation:

Calculate the slope m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (- 4, 0) and (x₂, y₂ ) = (0, 2) ← 2 points on the line

m = \frac{2-0}{0+4} = \frac{2}{4} = \frac{1}{2}
