The provided linear equation is y = 1.5x. The general form of the linear equation is \(\displaystyle{y}={b}_{{0}}+{b}_{{1}}{x}.\)

1. On comparing the provided linear equation with the general form of the equation, the y-intercept, \(\displaystyle{b}_{{0}}\) is 0 and the slope, \(\displaystyle{b}_{{1}}\) is 1.5.

2. The slope of the line is +1.5, so the gradient is +1.5. The slopes upward as the line moves from left to right.

3. Considering the provided equation, the values of y for x = –6 and 6 is obtained as:
