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
