So let's look at first what slope-intercept form is. Slope intercept form is actually y equals mx plus b. The reason why it is called slope intercept form is because it gives a slope and an intercept.

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 may ...

Higher - The gradients of two perpendicular lines will always multiply to make –1. Make sure you are familiar with finding the equation of a line and calculating gradient to understand equations of ...
