​In this module, you will be able to:

 write the linear equation ax + by = c in the form y = mx +b and vice versa. M8AL-If-1

​

Specifically, you are expected to:

1. write linear equations from standard form ax + by = c to slope- intercept form y = mx +b; and

2. write linear equations from slope- intercept form y = mx +b to standard form ax + by = c.
