Question

Which function is best represented by the graph?

Answer 1

The answer is J

Explanation:

the y-intercept is 8 and to find the slope you count rise over run, well the graph is too small to tell what points are actually on the lines, but it's given that (0,8) and (6,0) are points. making the rise/run= to 8/6 and then simplify to 4/3. and you can tell that the slope is negative because it's going downward from left to right.

Answer 2

J

Explanation:

First look at the y-intercept. When y=0, you get 8 on the graph, so in the equation it has to give you 8 as well.

This narrows it down to F G J

Next, the slope of the graph is negative because its tilting downwards.

This narrows it down to G J

Finally, on the graph when y=0, you get 6, so the equation has to meet this too

With your choices narrowed down to G and J, calculate the x-intercepts.

0= -4/3x+8

-8= -4/3x

-8(-3/4)=x

x=6
