The graph for the equation y = 2 x + 4 is shown below. On a coordinate plane, a line goes through (negative 2, 0) and (0, 4). If another equation is graphed so that the system has one solution, which equation could that be? y = 2 x minus 4 y = 2 (x + 2) y = 2 (x minus 4) y = x + 4

  y = x + 4

Step-by-step explanation:

The system will have one solution if the second equation has a slope that is different from the slope in the first equation.

The first equation is ...

  y = 2x +4

It is of the form ...

  y = mx + b

where m is the slope, and b is the y-intercept.

Any equation with the same slope (x-coefficient) will have a graph that is coincident with, or parallel to y = 2x+4. So, for the system to have exactly one solution, the slope must be different.

The offered equations all have an x-coefficient of 2, except the last one:

  y = x +4 . . . . . x-coefficient is not 2.

This is the equation that will give one solution when graphed with the given equation.

describing distributions is one of the key skills you’ll need to earn a high score on the ap statistics exam. if you need proof of this, just flip through some past exam questions, which can be found at the collegeboard website. you’ll notice that the first free response question is almost always a question requiring you to look at a graph and describe it.
