Summary of Linear Equations

Casandra Ong- 18Aug

1) Discuss if there is an equation, when c is not the y intercept.
2) At y-intercept, x is 0
3) c is not always the intercept. For example, y= 1÷x + c. Therefore, the value of y is undefined when x=0 and c would not be the y- intercept.
4) x= -c÷m
5) m= gradient
= (change in y-coordinate) ÷ (change in x-coordinate)
