HELP PLEASE math questions: 1. Fill in the blanks to describe how you could identify the number of solutions to a system if you only
knew some points on each line.
Start by finding the of each line using the points.
Compare the slopes. If they are different, the lines . This means there is
solution to the system.
You could also plot the points on a and use this to find the point where the
lines.

2. . Identify the number of solutions from the description of the equations.
Two equations are the same on one side but different on the other. ANSWER:
One of the equations in the system can be rewritten so it is identical to the other equation. ANSWER:

3.Adding the equations in a system of equations can sometimes be helpful in solving a system of
equations. Explain why.
