Question

The scatter plot and line of best fit above shows the Olympic Games winning men's pole vault from 1908 to 2004. Which of the equations below best describes this graph?

A. y = 1/4 x + 3.5

B. y = 0.025x + 3.5

C. y = -1/4 x - 3.5

D. y = 40x - 140

Answer 1

its probably a ithink

Answer 2

We can eliminate C and D because the y-intercept is 3.5.
Remember this: y=6x+9
6 is the slope.
9 (or (0, 9)) is the y-intercept.
The answer is B because when you calculate the slope (5.9-5.1 divided by 96/64) you get 0.025.
