Which equation of a line of best-fit reflects a negative correlation?
y = StartFraction 1 Over 70 EndFraction x + 312
y = StartFraction negative 83 Over negative 27 EndFraction x + 15
y = 8 x minus 2
y = negative 6 x + 13

y = negative 6 x + 13

Step-by-step explanation:

A negative correlations implies that the slope is negative, so you just have to solve for y for each to see if slope was negative,

hence the last equation y=-6x+13

y = negative 6 x + 13

Step-by-step explanation:my dude i got it right on edge

arrange the equations with like terms in columns.

analyze the coefficients of x or y.

add the equations and solve for the remaining variable.

substitute the value into either equation and solve.

check the solution.
