What you'll learn
Each question helps you build key knowledge and skills.
- 1In y = mx + c, m is the gradient (steepness) and c is the y-intercept.
- 2The y-intercept is where the line crosses the y-axis, at x=0.
- 3A positive gradient means the line slopes upward left to right; negative means downward.
- 4To find a y-value, substitute the x-value into the equation.
