Question

Find the gradient of the straight line that goes through points (2,8) and (4,16)

Answer 1

gradient = 4

Explanation:

calculate the gradient m using the gradient formula

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

let (x₁, y₁ ) = (2, 8 ) and (x₂, y₂ ) = (4, 16 )

substitute these values into the formula for m

m =
`(16-8)/(4-2)` =
`(8)/(2)` = 4
