Question

Draw a negative linear relationship. Label it R. Along a curve showing a linear​ relationship, how does y change for each increase in x of one​ unit? For each increase in x of one​ unit, y​ _______.

Answer 1

For each unit increase in x ; y decreases by 2 units.

Explanation:

A negative relationship between two variables, X and Y is depicted d on a scatter plot by a negative trend line or slope. A negative relationship is interpreted as the decrease in variable X as Y increases or vice versa.

The scatter plot attached is related by the linear model :

y = - 2x + 110

Here, the slope of the plot is - 2 ; this means that for every unit increase in x - axis, then the y values decrease by 2 units.
