What's that step?
What is Slope Form?
y=mx+b
What does the solution on a graph represent?
The point where the two lines intersect.
Identify the substitution:
3x+9y=87
y= 6x-2
y= 6x-2
What is the goal of the elimination method?
To eliminate (get rid of) one variable by adding or subtracting equations.
What is it called when you give a person a lot of compliments, even if they do not need them?
Glazing
In what form should your complete answer be in?
(x,y)
What is the solution?
y=x+1
y=x+3
No solution, because they are parallel lines.
Solve the system
y= 4x-5
2x+y=7
Solution: (2,3)
What happens if you add the equations?
x+y=5
x-y=1
The "y" is eliminated (cancels out).
Who did Mike Tyson fight and lose to?
(Ms. Jemison was very upset at this)
Jake Paul
What form does a problem have to be in for graphing to work?
Slope Form
If two equations graph to the same line, how many solutions exist?
Infinitely many solutions.
y=-2x+4
3x+y=10
Solution: (6,-8)
Solve:
x+y=7
x-y=3
What is the name of the talking toilet?
Skibidi Toilet
What button do you press on the calculator to find the intersection of two equations?
Press 2nd then "Calc" and select intersect.
y+2x=5
y=x-1
Solution:(2,1)
y=3x-7
2x+y=11
Solution: (18/5, 19/5)
Solve:
2x+3y=13
4x-3y=5
Solution: (3, 7/3)
The slang word for "I'm doomed" or "I'm done for"
I'm cooked
If you are using the elimination method, and you change the bottom expression to be negative, does it only affect the first coefficient?
No! It changes the sign of the entire expression.
2x+y=13
x+2y=14
Solution: (4,5)
y+4x=9
3x-2y=-6
Solution: (1 1/11, 4 7/11)
Solve:
3x+2y=16
2x-y=3
Solution: (22/7, 23/7)
