Answer:

A

Step-by-step explanation:

2x is the parent function and -6 is the y intercept

Answer:

A

Step-by-step explanation:

The y intercept is when x = 0.

In that case y = - 6 just from reading the graph.

So far what you know is

y = mx - 6

So B and C are both incorrect.

Now you need the slope. That can be calculated from the x and y intercept.

  • x intercept: (3,0)
  • y intercept: (0,-6)
  • Slope formula
  • m = (y2 - y1)/(x2 - x1)

m = (0 - -6)/(3 - 0)

m = 6 / 3

m =  2

y = mx - 6

y = 2x - 6

The answer is A
