We are going to calculate in over in,or the over the.
Here are examples for your lines:

Find the slope of the straight line that passes through (, ) and (, ) or state that the slope is undefined. Then indicate if the line through the points:
(left to right), ……………this will be in case when has positive value
(left to right), ……………this will be in case when negative value
is , ……………this will be in case when is equal to
or is ……………. this will be in case when is undefined

1.
If the straight (for example)line that passes through (4,1) and (-2,1),then slope is:


Plug in and values into slope formula

………….. Simplify


The slope of the line is .
Since the , the would be .

2.

If the straight line that passes through (-2, 3) and (-2, 5)



Plug in and values into slope formula

………….. Simplify

The slope of the line is .
Since the is, the would be .
3.

find the slope going from (-2,0) to (-1,-2)


Plug in and values into slope formula

………….. Simplify



4.
find the slope passing through (1,0) to (-1,1)

Plug in and values into slope formula

………….. Simplify
