Here’s a graph of a linear function. write the equation that describes that function. express it in slope-intercept form.

y = (1/3)x + 4

Step-by-step explanation:

Two points on this straight line are (-9, 1) and (0, 4).

As we move from the first point to the second, x increases by 9 and y by 3.  Thus, the slope of this line is m = rise / run = 3/9, or m = 1/3.  

The y-intercept is easily read off the graph:  it is (0, 4).  Thus, b = 4 in the slope-intercept form of the equation of a straight line, y = mx + b:

y = (1/3)x + 4

This is the desired linear function.

x+y=90

x=30-y=x

if you understand you will get the answer

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.
