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

(A)

Step-by-step explanation:

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

The equation which can be simplified to find the slope of the trend line in the scatterplot is

The correct option is A.

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)

thats not a system of equations, that is a solution
