Question 3 • Mathematics 8

Which regression line properly describes the data relationship in the scatterplot?

Answer
A
Image with description A scatterplot is shown on a first quadrant coordinate plane. The x axis ranges from 0 to 7 in increments of 1. The y axis ranges from 0 to 7 in increments of 1. There is a point at (1 point 5 comma 3). There is a point at (3 comma 5). There is a point at (3 point 5 comma 3 point 5). There is a point at (4 comma 5). There is a point at (5 comma 4). There is a point at (5 point 5 comma 6). A line passes through (0 comma 2 point 5), and (4 comma 4 point 5).
B
Image with description A scatterplot is shown on a first quadrant coordinate plane. The x axis ranges from 0 to 7 in increments of 1. The y axis ranges from 0 to 7 in increments of 1. There is a point at (1 point 5 comma 3). There is a point at (3 comma 5). There is a point at (3 point 5 comma 3 point 5). There is a point at (4 comma 5). There is a point at (5 comma 4). There is a point at (5 point 5 comma 6). A line passes through (2 comma 4) and (5 comma 6).
C
Image with description A scatterplot is shown on a first quadrant coordinate plane. The x axis ranges from 0 to 7 in increments of 1. The y axis ranges from 0 to 7 in increments of 1. There is a point at (1 point 5 comma 3). There is a point at (3 comma 5). There is a point at (3 point 5 comma 3 point 5). There is a point at (4 comma 5). There is a point at (5 comma 4). There is a point at (5 point 5 comma 6). A line passes close to (2 comma 2) and close to (5 comma 5).
D
Image with description A scatterplot is shown on a first quadrant coordinate plane. The x axis ranges from 0 to 7 in increments of 1. The y axis ranges from 0 to 7 in increments of 1. There is a point at (1 point 5 comma 3). There is a point at (3 comma 5). There is a point at (3 point 5 comma 3 point 5). There is a point at (4 comma 5). There is a point at (5 comma 4). There is a point at (5 point 5 comma 6). A line passes through (1 comma 2) and (5 comma 4).
