Answer:
3 + x
Step-by-step explanation:
Sum means to add, so you would just add 3 and x (since they haven't given an actual number and only a variable).
For this case we have by definition, that the equation of a line in the slope-intersection form is given by:

Where:
m: It is the slope of the line
b: It is the cut point with the "y" axis
We have, according to the data provided, that the line is of the form:

That means that the slope is -1.
ANswer:

-mn^2-5m^2/(5m-2)(m+4n)
if I did it correctly
5.008
As a fraction: 5008 / 1000
As a mixed number: 5 and 8/1000
Answer:
the y -intercpt is the 3
the slope is -3/4
Step-by-step explanation:
this is because the 3 is the starting point on the y-axis and the slope is -3/4 because you are going down 3 to the right 4 ---hope this helps
