Question

Whats the answer please

Answer 1

y- intercept = 4 , slope = 2

Explanation:

(a)

The y- intercept is the point on the y- axis where the line crosses it.

The line crosses the y- axis at (0, 4 )

Then the y- intercept is 4

(b)

calculate the slope m using the slope formula

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

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

substitute these values into the formula for m

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