base=42 m

height=h=?

base angle θ=60°

tan 60=h/42

Answer:

Slope = -2

Step-by-step explanation:

Since, slope = $\frac{\text{Rise}}{\text{Run}}$

Rise = -(y-intercept)

Run = (x-intercept)

From the graph attached,

y - intercept = -(4) = -4

x - intercept = 2

Therefore, slope the line given in the graph attached will be,

Slope = $\frac{-4}{2}$ = -2

Slope = -2
