Question

thanks

Answer 1

The x-intercept is where the graph of the line passes through the x-axis.

To get on the x-axis, the y-coordinate must be zero.

y = 2x - 5

0 = 2x - 5 Solve for x. @cutegirl

Answer 2

2.5

Answer 3

so zero?

Answer 4

Correct. I think of it as 5/2 but it is 2.5 as well.

Answer 5

The coordinates of the x-intercept in this problem are this:

( 2.5, 0 )

Answer 6

so wait its not c?

Answer 7

Look at the options. Is there a 2.5 or a 5/2 which is the same thing?

That is what the x-intercept is.

Answer 8

yep there is

Answer 9

Going back to the original equation:

y = 2x - 5

and substituting x = 5/2 for x,

y = 2*(5/2) - 5

y = 5 - 5 = 0

which tells us that the x-intercept of 5/2 is correct.
