Question

1. select the appropriate linear model for the scatter plot below.

a ( y = -x + 0.5 ) c ( y = x + 0.5 )
b ( y = -x - 0.5 ) d ( y = x - 0.5 )

Explanation:

Step1: Check slope direction

The line has a positive slope, so eliminate A and B (negative slopes).

Step2: Check y-intercept

The line crosses the y-axis near -0.5, so eliminate C (y-intercept 0.5).

Step3: Confirm correct model

Only D has positive slope and y-intercept -0.5, matching the plot.

Answer:

D. \( y = x - 0.5 \)
