Question

point a has coordinates of (3.6)
A) write down the coordinates of point B
B) find the gradient of line AB

Answer 1

Answer:

see explanation

Step-by-step explanation:

(a)

The coordinates of point B (7, 1 )

Calculate the slope using the slope formula

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

with (x₁, y₁ ) = A (3, 6 ) and (x₂, y₂ ) = B (7, 1 )

$m_{AB}$ = $\frac{1-6}{7-3}$ = $\frac{-5}{4}$ = - $\frac{5}{4}$
