Question

Without drawing a graph find the intercepts of each line. y+5=–2x

pls help i dont know what this means.

Answer 1

see explanation

Explanation:

The intercepts are where the line crosses the x and y axes.

To find the x- intercept ( where the line crosses the x- axis) let y = 0 in the equation and solve for x, that is

0 + 5 = - 2x

5 = - 2x ( divide both sides by - 2 )

x = -
`(5)/(2)` = - 2.5 ← x- intercept ⇒ (- 2.5, 0 )

To find the y- intercept ( where the line crosses the y- axis ) let x = 0 in the equation and solve for y, that is

y + 5 = 0 ⇒ y = - 5 ← y- intercept ⇒ (0, - 5 )
