nikdorinn [45]

Answer: x < 30

Which equation represents the graph function?
DENIUS [597]

Answer:

See below.

Step-by-step explanation:

First, it's obviously a line so the equation is a linear equation.

In order to find a linear equation, we first need the slope and the y-intercept. Recall the slope-intercept form: y=mx+b, where m is the slope and b is the y-intercept.

We already know the point (0,3) which is the y-intercept. Thus, b=3.

To find the slope, use the slope formula:

m=\frac{\Delta y}{\Delta x} =\frac{2-3}{3-0}=-1/3

Thus, the equation is:

y=-\frac{1}{3}x+3
