Revise how to work out the gradient of a straight line in maths and what formula to use to calculate the value change in this Bitesize guide.

GCSE Eduqas Straight line graphs - Eduqas y = mx + c y = mx + c is an important real-life equation. The gradient, m, represents rate of change (eg, cost per concert ticket) and the y-intercept, c ...

The y-intercept is the point at which a linear equation crosses the y-axis on the x=0 plot point. The equation to determine both the slope and the y-intercept of a line is y=mx+b. This calculation ...
