Question

Determine the gradient of ef if e(-5;-2) and f(2;1)

Answer 1

Answer:

Step-by-step explanation:

E ( -5 , -2)  & F(2 , 1)

Gradient / Slope = $\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}$

                    $= \dfrac{1-[-2]}{2-[-5]}\\\\\\=\dfrac{1+2}{2+5}\\\\\\=\dfrac{3}{7}$

Answer 2

Answer:

3/7

Step-by-step explanation:

Slope = y_2 - y_1/x_2 - x_1

Here

y_2 = 1

y_1 = -2

x_1 = -5

x_2 = 2

m = 1 - (-2)/2 - (-5)

m = 1 + 2/2 + 5

m = 3/2 + 5

m = 3/7
