Please do not copy work from sites that do the work.
This is your opportunity to think and provide your thoughts and understanding to the Unit.
1) Solve the system using substitution or graphing:
x + y = 72
1x
– 3y = -12
4,2
a) What is the point of intersection for the system (2 points + 2 points for exact answer):
The intersection would be 12
b) Complete the sentence: I know this is the point of intersection because (5 points).
I know this is the point of intersection because both the lines intersect at this point
3) From the table ( 5 points)
2) Complete the table of values for the two
equations (10 points, +4 for exact answers)
Use your own values for x:
Value of x: x + y = 72 x – 3y = -12
+
Which points are y-intercepts?
How do you know?
These are the point(s) of the y-
intercept because:
