Question

Which model best fits the data shown in the scatterplot?

A. y=-0.7x+1.9
B. y = 0.7x+1.9
C. y=-0.7x-3.8
D. y=1.9x-07

Answer 1

A. y = -0.7x + 1.9

Explanation:

• The y-intercept is roughly +2 as you can see from the scatterplot therefore ⇒ Not option C or D [both of which are negative]
• The slope is slanted from top left to right bottom [meaning the slope is negative] ⇒ Not B
• The correct option is A
