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

The x-intercept is the point where the line meets the x axis, which is the set of points where the y coordinate is zero.

So, you set y=0 and solve for x:

So, the point is (4/3, 0)

so, converting firstly the mixed fractions to improper fractions and then "adding".

i believe it's a.

i'm not sure on this one, most likely correct.
