With those preliminaries out of the way, we can define our equations to plot. To plot a linear equation, remember that the slope-intercept form is y = mx + b, where "m" is the slope, or steepness ...

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 ...

Revise how to plot a linear equation graph. Learn how to read x and y coordinates from a graph in this BBC Bitesize maths KS3 guide.

The graph of a oblique straight line is described using the equation, 𝒚 = 𝒎𝒙 + 𝒄 Graphs of two or more straight lines can be used to solve simultaneous linear equations.
