The values on the x-axis range from 0 to 6 in increments of 1. The values on the y-axis range from 0 to 100 in increments of 10. The line begins at the origin and slopes upward from left to right, ending at left parenthesis 4.5 comma 90 right parenthesis. The following points are plotted on the graph: left parenthesis 1 comma 60 right parenthesis, left parenthesis 1 comma 70 right parenthesis, left parenthesis 2 comma 70 right parenthesis, left parenthesis 2.5 comma 75 right parenthesis, left parenthesis 3 comma 74 right parenthesis, left parenthesis 3 comma 80 right parenthesis, left parenthesis 3.5 comma 80 right parenthesis, left parenthesis 4 comma 85 right parenthesis, left parenthesis 4.5 comma 90 right parenthesis, and left parenthesis 5 comma 90 right parenthesis.

A linear regression is appropriate. Fitting y on x gives approximately

y ≈ 6.65x + 57.78,

so a straight-line model with positive slope matches the roughly linear upward trend in the data.
