The x-intercept is a point whose y-coordinate is 0, so (x,0).
Substitute 0 for y in the equation:

The x-intercept is

.
Well you would do $1.75 x 1,000. That would be 1,750$.
Then you would take away that 95$ they spent buying the box of tea bags and their total would be 1,750$ - 95$ = 1,655$.
8 + 6.2 + 4a - 9a
(8 + 6.2) + (4 - 9)a
14.2 - 5a is your answer.
