PLEASE HELP!!!! I REALLLY NEED HELP!!!! PLEAE HELP!!!!!!

Answer 1

y- intercept = 4 , gradient = 2

Explanation:

(a)

the y- intercept is the value of y on the y- axis where the line crosses

here the y- intercept = 4

(b)

calculate the gradient m using the gradient formula

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

with (x₁, y₁ ) = (- 2, 0) and (x₂, y₂ ) = (0, 4) ← 2 points on the line

m =
`(4-0)/(0-(-2))` =
`(4)/(0+2)` =
`(4)/(2)` = 2
