Question

On the Guardian lines a and B

Answer 1

2 and - 1

Explanation:

Calculate the gradients using the slope formula

m =
`(y_(2)-y_(1) )/(x_(2)-x_(1) )`

with (x₁, y₁ ) = (- 2, -3) and (x₂, y₂ ) = (3, 7) ← 2 points on line A

`m_(A)` =
`(7+3)/(3+2)` =
`(10)/(5)` = 2

with (x₁, y₁ ) = (- 2, 7) and (x₂, y₂ ) = (7, - 2) ← 2 points on line B

`m_(B)` =
`(-2-7)/(7+2)` =
`(-9)/(9)` = - 1
