## Answers (1) 2020-11-30
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: ### Relevant Questions asked 2020-11-05
