Question

Pls help!!
Write an equation to show the proportional relationship in the table.

Answer 1

y=65x

f(x)=65x

Explanation:

Let x be time and y be trees planted.

Using the generic equation y=mx+b we can assume "Trees planted=slope x Time+y intercept.

We find the slope, 65, by using the formula m=y2-y2/x2-x1.

m=325-130/5-2

m=195/3

m=65.

Now, to find the y-intercept, let's replace the known variables with unknown ones.

130=65(2)+b

130=130+b

130-130=b

b=0

The result is y=65x.

In function notation, f(x)=65x.
