Question

Find the x and y intercepts of the equation 8x+y=-9

Answer 1

see explanation

Explanation:

To find the intercepts, that is where the graph crosses the x and y axes.

• Let x = 0, in the equation for y-intercept

• Let y = 0, in the equation for x-intercept

x = 0 : 0 + y = - 9 ⇒ y = - 9 ⇒ (0, - 9 ) ← y- intercept

y = 0 : 8x + 0 = - 9 ⇒ x = -
`(9)/(8)` ⇒ ( -
`(9)/(8)`, 0) ← x- intercept
