Answer:
or in slope y-intercept form :
Step-by-step explanation:
The easiest way of find the answer for this is to use what is called the "point-slope" form of a line, because you are in fact given the value of the slope (m) and also a point it goes through:
In our case the equation becomes:
This can also be written in the slope-intercept form by solving for "y" and operating to remove the parenthesis:
