Question

Identify the x and y intercepts from the following equation:y = 2x + 4

Answer 1

The y-intercept is found when x = 0. Replacing x = 0 into the equation we get:

y = 2(0) + 4

y = 4

Then, the y-intercept is (0, 4)

The x-intercept is found when y = 0. Replacing y = 0 into the equation we get:

0 = 2x + 4

-4 = 2x

-4/2 = x

-2 = x

Then, the x-intercept is (-2, 0)
