A basketball player averages 13.5 points per game. Use this rate to find the value of x, the number of points scored in 7 games.

xxTIMURxx [149]

Knowing that a ratio applies to the same situation in just a larger/smaller scale;

(13.5)(7)=x (where x is the predicted number of scores)

94.5=x

Therefore, the player should score 94.5 points in 7 games.

Hope I helped :)

What is the equation of the line graphed below?

andrew-mc [135]

Answer: $y=-\frac{1}{3}x$

Step-by-step explanation:

From the origin we can see to get to the point plotted we have to go down 1 and right three giving us the slope $\frac{-1}{3}$

These are in the form of y=mx+b

b is the y-intercept and m is the slope

since the y-intercept is 0 b is 0 and isn't need leaving us with y=mx

We can put our slope into the equation giving us the answer in C
