Question

What is the gradient of the line that goes through coordinates (2,3) and (4,9)

3

2/6

1/3

Answer 1

gradient = 3

Explanation:

Calculate the gradient ( slope) using the slope formula

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

with (x₁, y₁ ) = (2, 3) and (x₂, y₂ ) = (4, 9)

m =
`(9-3)/(4-2)` =
`(6)/(2)` = 3
