Question

Which ordered pairs represent points on a graph of the equations? Select all that apply.

y = -7/4x + 1/2

(-5, 3)
(0, -6)
(-2, 4)
(2, 6)
(-3, -2)
(5, -1)

Answer 1

(-2,4)

apparently only one seems to be correct.

Answer 2

(-2,4)

Explanation:

If you have a scientific calculator, go to the Y= button at the top left. Put your equation into the calculator. Next, Press the buttons 2nd and then Graph (which will be labeled "TABLE" in blue ontop of the button 'Graph'). You can check all your answers on the table. (-2,4) is the only valid answer because on the table, the x-value is 2 and the y-value is 4. When you look at the ordered pairs on your calculator, your y-value are all fractions.

Hope this helped! Let me know in the comments if you got it right or not.
