Regarding a straight line, what is the relationship between the gradient and the y-intercept?
They determine the equation of the line.
They are always equal to each other.
The gradient indicates the slope, while the y-intercept is where the line crosses the y-axis.
They are both constants in the equation y = mx + c.
