## twilliams785 3 years ago Choose the correct x-intercept and y-intercept of the equation 2x - y = 4. Answer x-intercept: (−4, 0), y-intercept: (0, 2) x-intercept: (−4, 0), y-intercept: (2, 0) x-intercept: (2, 0), y-intercept: (0, −4) x-intercept: (0, 2), y-intercept: (0, −4)

Solve for y: \[y = 2x - 4\] So y intercept is (0, -4) This narrows it down to the last two choices. The x intercept is (2,0) because the definition of x-intercept says that y is 0.

2. samjordon

x intercept is when y =0 2x-0=4 x=2 so x intercept is (2,0)

3. samjordon

Y intercept is when x =0 2(0)-y=4 y=-4 y intercept is (0,-4)

thank you guys so much, i find this stuff so confusing and i have no one explaining it to me.

np :)

If it confuses you, I would either plot it by hand or use something like wolfram|alpha. It's easier to understand with a picture: http://www.wolframalpha.com/input/?i=2x+-+y+%3D+4

i tried plotting it but i had no idea what i was doing so i gave up .
