Question

Which expression can be simplified to find the slope of the trend line in the scatterplot? On a coordinate plane, a line goes through points (2, 79) and (12, 24). StartFraction 24 minus 79 Over 12 minus 2 EndFraction StartFraction 24 + 79 Over 12 + 2 EndFraction StartFraction 24 minus 79 Over 2 minus 12 EndFraction StartFraction 24 minus 79 Over 12 + 2 EndFraction

Answer 1

a

Explanation:

Answer 2

(A)
`(24-79)/(12-2)`

Explanation:

Given the trend line which goes through (2, 79) and (12, 24).

`Slope, m=(y_2-y_1)/(x_2-x_1) \\x_1=2, y_1=79,x_2=12, y_2=24\\$Therefore$:\\\\m=(24-79)/(12-2)`

The equation which can be simplified to find the slope of the trend line in the scatterplot is
`(24-79)/(12-2)`

The correct option is A.
