The answer is C) 5/4.

Explanation:

To find the x-intercept, we must set the y-intercept to 0, then solve for x.

4x-3(0)=5, 4x-0=5, 4x=5, (4x)/4=5/4, x=5/4

C) 5/4

Explanation:

Hello!

Normally you would want to solve for y, but since you need to find the x-intercept, it would be wise to solve for x.

So we start with:
4x-3y = 5

Now, we can simply put 0 in for the y term because the x-intercept means 'when is the y value 0'?

This means the equation is now:

4x = 5

Now to get x by itself, divide by 4

x = 5/4

And that's your answer!

Hope this helps!
