The gradient of the given graph is 1.5

<h3>Calculating Gradient </h3>

From the question, we are to determine the gradient of the graph

Gradient is given by the formula

$m = \frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

Where m is the gradient

Picking the points (-2, -2) and (2, 4) on the line

Then,

x₁ = -2

y₁ = -2

x₂ = 2

y₂ = 4

Putting the parameters into the equation, we get

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

$m = \frac{4+2}{2+2}$

$m = \frac{6}{4}$

m = 1.5

Hence, the gradient of the given graph is 1.5
