HELP ME PLSSSSSSSssssss

Answer 1

Answer:

RoC is 0.75 (3/4); Equation is y=0.75x $(y=\frac34 x$)

Step-by-step explanation:

You can easily spot that first column, x increases by 1 each line, while the second, y, increases by 0.75.

Rate of change is variation in y divided by the variation in x, or $\Delta y \over \Delta x$ . Replacing with the value we found, we get that the rate of change is $\frac{0.75}{1}$ or $\frac34$.

To find the equation the easiest way is to go back 4 steps, at the same rate of change, in order to find what's the value for x=0. Going back by 0.75 each step starting from 4, we obtain 2.25, 1.5, 0.75, and finally 0. Our equation becomes$y=0.75x$
