Question

a line has an x-intercept of (4,0) and a y-intercept of (0,12).Find the slope of the line

Answer 1

-3

Explanation:

→ Utilise the gradient formula

`(y2-y1)/(x2-x1)`

→ Substitute in the values from the coordinates (4,0) and (0,12)

`(12-0)/(0-4)=(12)/(-4) =-3`

→ The gradient of the line is -3

Answer 2

m = -3

Explanation:

Slope Formula:
`m = (y2-y1)/(x2 - x1)`

All you have to do is plug in 4 for x1, 0 for x2, 0 for y1, and 12 for y2 and you should be able to calculate your answer!
