Step-by-step explanation:
<u><em>Answer:</em></u>
The missing term is 3x²
<u><em>Explanation:</em></u>
Addition and subtraction can only take place between like terms.
<u>For two terms to be like</u>, both the variable and its degree must be the same in both terms
<u>Now, consider the given terms:</u>
First term is 7x² has the variable x with degree 2
The resulting term is 10x² has the variable x with degree 2
This means that the missing term is ax²
We need to get the value of "a"
<u>This is done as follows:</u>
ax² + 7x² = 10x²
x²(a+7) = 10x²
a+7 = 10
a = 10-7
a = 3
Therefore, the missing term is 3x²
Hope this helps :)

Answer:
See attached picture.
Step-by-step explanation:
To graph the line, start at (0,-3) since b=
-3 in the equation. This is the y-intercept.
Mark this point. From this point, move
down 2 units and to the right 1 unit. Mark
this new point at (1,-1). Connect the points
with a line. See attached picture.
