Given an equation Q = 20 – 3P, which of the following statements is likely to be true?

A positive relationship exists between P and Q.

A plot of the equation will result in a graph with a positive slope.

P and Q exhibit a non-linear relationship.

Every time P increases by one unit, Q falls by three units.Correct

Explanation

The general linear relationship states that Y = a + bX, where a is the intercept and b is the gradient of the line. In the above equation, the value of Q is 20 when P is 0. For every increase of P by one unit, Q falls by three units; the negative relationship between the two variables is given by the negative sign.
