Answer:
(5,4) and (3,4)
Step-by-step explanation:
A line segment has 2 end points which can be denoted as:
and 
When this line segment intersects at y.
This means that the coordinate on the y axis is the same at both end points
i.e.

and
becomes
and 
x1 and x2 can be any value but the y value must remain unchanged
Using the above analysis, a possible coordinate is:
and 
Note that there are as many answers as possible as long as the coordinate pair satisfy is of the form
<em> and </em>
<em />
Take for instance, another possible pair is:
and 
Answer:
Step-by-step explanation:


80 x 4 = 79+81+77+x
320=237 + x
320-237 = x
83=x
so Marianne must score 83 points or higher on her last test
