Use algebraic rules of equations to predict the solution type to the system of
equations. Include all of your work for full credit.

\1.1
select the type of equation.
A and B are crossing in the ++ are off to the left. line b is much longer going down
to the left. - ANS - consistent
\1.2
What is the solution - ANS - (5,3)
\2.1
Select the types of equations. two parallel lines going from the left. they are in the
second block and end in the fourth block - ANS - inconsistant
\2.2
click on the solution set below until the correct one is displayed. - ANS - I got this
one wrong. It is NOT infinite set of points on the line.
\3.1
select the types of equations. it is a straight line that says a b on it and goes
almost directly though the middle but is off my a little bit. - ANS - equivalent.
\3.2
click on the solution set below until the correct one is displayed - ANS - infinite
set of points on the line
\4.1
select the types of equations
two lines that are NOT parallel they are going to meet in the first block soon. -
ANS - consistant
\4.2
click on the solution set below until the correct one is displayed. - ANS - point in
quadrant 1
