Consider the following linear regression prediction equation: y = 12 + –1x. what is the direction of the relationship between these two variables?

Step-by-step explanation:

given that the following linear regression prediction equation: Y = 12 + –1x

Here slope = -1

Whenever regression slope is negative, we can say that the two variables x and y are negatively correlated.

In other words, when y increases x decreases and vice versa.

The relationship between the variables is negative or inverse.

The graph of this line with negative slope shows the line as moving from top left to bottom right

Here slope = -1

Hence for unit increase in x, there is one unit increase in y.

your answer is the last one

step-by-step explanation:

divide the length of a'c' by the length of ac to get a scale factor of two

& then reflect vertically (over the y-axis)

so your answer is dilation by a scale factor of 2 followed by reflection over the y-axis
