# How do you write an equation of a line given y-intercept -8 and slope 3?

I have given a detailed explanation about how it all works.

Consider the standard form of the equation for a strait line:

Where

'~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

so equation (1) becomes:

'~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Suppose we put the value of the y-intercept (given as -8) into the equation were

So for the equation of a strait line the

Change the value of c moves the plotted line up or down

Imagine for a moment that

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
