Equations Of Linear Graphs
Gbogbo ọrọ náà
Every straight line can be captured in one tidy equation, \(y = mx + c\), where two numbers tell you everything: the gradient and where the line crosses the y-axis. Read those two numbers and you can draw the line; draw the line and you can read them back.
In this lesson you will interpret and find the equation of a straight-line graph in the form \(y = mx + c\), identifying the gradient and the y-intercept.
