GCSE Maths - What on Earth is y = mx + c #67

The video tutorial explains why line equations are often written in the form y = mx + c, highlighting the convenience of this format for comparing and graphing lines. It details the roles of m (gradient) and c (y-intercept) in determining a line's slope and where it crosses the y-axis. Through examples, the video demonstrates how to plot lines and rearrange equations into the standard form. It also addresses special cases where equations appear to lack m or c values, explaining how to interpret these situations.

Describe how to determine the gradient and y-intercept from the equation 4y plus 16 equals 2x.

What does it mean if an equation does not have a c value in the form of y equals mx plus c?
