2. Which ordered pair is a solution of y = x – 4? (1 point)
(−1, −5) (0, −3) (2, 6) (3, 1)
3. Which is a graph of the equation y = 2x − 4? (1 point)
4. Which equation has (2, −1) as a solution? (1 point)
y = 2x − 1 y= x+ 3 y= x– 3
y = −2x + 1

  1. #2. Just check each (x,y) pair to see whether y = x-4
    -5 = -1-4, so (-1,-5) is a solution

    #3 any function of the form y = mx+b where m and b are just numbers, is a straight line

    #4 Just like #2. Plug in x and y to see whether the equation is true.
