What is the function shown in this graph.

answer:

f(x)= -2x+3, Answer choice C would be the answer.

Step-by-step explanation:

First look at your line and see how its going downward or right to left. You can automatically determine it is a negative slope.

Next you want to rise over run (but for a negative slope it would be falling and running). Let's start with the given points. Start with (0,3) and go to the next point. You would fall 2 and run once meaning the fraction would look like -2/1. Your slope would then be -2. Next you y-intercept would be based on where your line crosses the y-axis (which is the point we used earlier (0,3).

Now set this up as slope intercept form except as a function, f(x)= -2x+3. -2x being the slope and 3 being your y-intercept.

your answer would be 12
