$slope = 2$ $"slope "=2$

Explanation:

$to calculate the slope m use the gradient formula$ $"to calculate the slope m use the "color(blue)"gradient formula"$

$∙ x m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}$ $•color(white)(x)m=(y_2-y_1)/(x_2-x_1)$

$let (x_{1}, y_{1}) = (- 4, 3) and (x_{2}, y_{2}) = (- 2, 7)$ $"let "(x_1,y_1)=(-4,3)" and "(x_2,y_2)=(-2,7)$

$m = \frac{7 - 3}{- 2 - (- 4)} = \frac{4}{2} = 2$ $m=(7-3)/(-2-(-4))=4/2=2$
