Question

the scatter - plot shows the relationship between two variables, x and y. a curve of best fit for the data is also shown. at x = 60, which of the following is closest to the y - value predicted by the line of best fit? a 190 b 210 c 250 d 270

Explanation:

Step1: Locate x - value on graph

Locate x = 60 on the x - axis.

Step2: Find corresponding y - value

Move vertically up from x = 60 until reaching the curve of best - fit, then move horizontally to the y - axis to estimate the y - value.
By visual inspection of the graph, when x = 60, the y - value on the curve of best - fit is approximately 250.

Answer:

C. 250
