Question

Here is a linear equation: y = 4x+2.
What is the x-intercept of the equation?

Answer 1

-1/2

Explanation:

set y equal to zero and solve for 'x'

0 = 4x + 2

-2 = 4x

-2/4 = x

x = -1/2

Answer 2

X INTERCEPT = -0.5

Explanation:

To find the X intercept you simply replace the Y with a zero.

this would make it 0=4x+2

now you solve it as usual.

0=4x+2

-2=4x

-2/4=4x/4

-0.5=x

x=-0.5
