1 A function is represented by the following set of
ordered pairs.
{(-3,-13), (0, -7), (3, -1), (6,5)}
Which equation represents the function?
A y = 3x - 7
B y = 6x - 7
c y=2x - 7
Dy=2x-7

Answer:

  C.  y = 2x -7

Step-by-step explanation:

You can use any pair of points to find the slope. Use the slope formula:

  m = (y2 -y1)/(x2 -x1)

  m = (-7 -(-13))/(0 -(-3)) = 6/3 = 2

This is the coefficient of x in the slope-intercept form ...

  y = mx +b

The second point (0, -7) tells you that b = -7, so the equation is

  y = 2x -7 . . . . matches C
