Answer:

y = (24/5)x + 24

Explanation:

Knowing that the parent equation for linear functions is "y = mx+b", where "m = slope" and "b = y-intercept", we can create an equation for the line of best fit.

We also need to know the formula for using two points to find the slope is "(y2 - y1)/(x2 - x1)", where (x2, y2) is a point on the graph and (x1, y1) is a point on the graph.

Finding the slope:

I will be using points (5, 48) and (0, 24).

(24 - 48)/(0 - 5)

(-24)/(-5)

24/5 is the slope so "m = 24/5"

We can tell from the graph (0, 24) is the y-intercept, so "b = 24"

Final equation:

y = (24/5)x + 24
