Can u guys help me i need help

Answer 1

slope = 40

Explanation:

calculate the slope m using the slope formula

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

let (x₁, y₁ ) = (0, 0) and (x₂, y₂ ) = (10, 400) ← 2 points on the line

m =
`(400-0)/(10-0)` =
`(400)/(10)` = 40

the slope of the line m = 40

which gives the speed of the train, that is 40 mph
