Question

The line I passes through the points (-4, 0) and (1, –1).
Find the gradient of line L.

Answer 1

gradient = -
`(1)/(5)`

Explanation:

calculate the gradient ( slope ) m of the line using the slope formula.

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

with (x₁, y₁ ) = (- 4, 0 ) and (x₂, y₂ ) = (1, - 1 )

m =
`(-1-0)/(1-(-4))` =
`(-1)/(1+4)` = -
`(1)/(5)`
