1. Find the slope and intercept for the line 2y-x-4=0

To find the slope and intercept of a line, first put the function into the form:

When this is done, m is the slope and b is the intercept. Now put your line into that form.

Now that this is in the same form as the equation above, it's easy to see that:

Slope =
Intercept =

2. Find the slope and intercept for the line 6/9y+2/3x-5=0

As in problem 1, just rearrange the equation into the form . The slope is and the intercept is .

From this you can see that:

Slope =
Intercept =

3. For ...
