Answer:
What the other guy said, he’s correct! :)
Answer: 
Step-by-step explanation:
To find the slope of the line , we will write the equation in the form:
where:
slope
y - intercept.
To write
in this form , we will make y the subject of the formula.
Subtract 4x from both sides

Divide through by 2
Therefore :

Steps
find the Least Common Multiple of the denominators (which is called the Least Common Denominator).
Change each fraction (using equivalent fractions) to make their denominators the same as the least common denominator.
Then add (or subtract) the fractions, as we wish!
your denominators stay the same so its 20
