Question

Which equation is the BEST fit for the data in the graph

Answer 1

C. Since the data is going down by -8, and it starts at +45

Answer 2

y = -8x + 75 (C)

Explanation:

To find this, you first should take a look at the y-intercept (The point at which x=0) to narrow it down a bit. In this case, the y-intercept is 75. The standard form of a linear equation is y = mx + b, where b is the y-intercept. Since there is only 1 answer where b is equal to 75, C is the right answer.
