Question

What is the gradient of the blue line?

Answer 1

Explanation:

the gradient means the tan value of the line

tan = y/x

= 6/ 3 = 2

Answer 2

gradient = 2

Explanation:

calculate the gradient ( slope ) m using the slope formula

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

with (x₁, y₁ ) = (2, 2) and (x₂, y₂ ) = (5, 8) ← 2 points on the line

m =
`(8-2)/(5-2)` =
`(6)/(3)` = 2
