Answer
The slope of the line = -1
Step-by-step explanation
The slope of a line is calculated by picking two different random points on the line with coordinates (x₁, y₁) and (x₂, y₂)
Slope = (y₂ - y₁) ÷ (x₂ - x₁)
So, for this question, if we take two random points on the line, from the graph sent, I'll pick points (-2, 2) and (-7, 7)
x₁ = -2
y₁ = 2
x₂ = -7
y₂ = 7
Slope = (7 - 2) ÷ (-7 - (-2))
= 5 ÷ (-7 + 2)
= 5 ÷ -5
= -1
Hope this Helps!!!
