Question

Find the values of the x-intercept and y-intercept of the graph of 2x + 3y = -6

Answer 1

see explanation

Explanation:

When the graph crosses the x- axis the y- coordinate is zero.

let y = 0, in the equation for x- intercept

y = 0 : 2x = - 6 ⇒ x = - 3 ⇒ (- 3, 0)

When the graph crosses the y- axis the x- coordinate is zero

let x = 0 , in the equation for y- intercept

x = 0 : 3y = - 6 ⇒ y = - 2 ⇒ (0, - 2)
