... • A scalar is a mathematical quantity whose value does not depend on the orientation of a coordinate system. The magnitude of a vector is a true scalar since it does not change when the coordinate axis is rotated. However, the components of vector (Ax, Ay) and (Ax′, Ay′), are not scalars. • It is po ...

... As the line is parallel to the line y = 3x + 8, the gradient must be 3. So the equation of the line must be y = 3x + c. To find the value of the y-intercept, c, we use the coordinates of the point that it passes through. Putting x = 1, y = -2 into the equation y = 3x + c gives, ...
