Question

Given: y = 3x - 4. What is the x-intercept? (4/3, 0) (0, -4) (0, 4/3).

Answer 1

(4/3,0)

Explanation:

y=3x-4

0=3x-4

0+4=3x

4/3=3x/3

4/3=x

(4/3,0)

Answer 2

(4/3, 0)

Explanation:

The x-intercept is where the line crosses the x-axis, which means that the y-value of the coordinate must be zero.

Thus, you set y in that equation to be zero.

0 = 3x - 4

Now you just solve for x.

4 = 3x

4/3 = x
