What is the solution?
(-1,1)
Solve the systems of equations using substitution:
-3x + 4y = -2
y = -5
What is (-6, -5)
Solve the systems of equations using Elimination:
14x + 2y = 26
-14x - 6y = -50
What is (1, 6)
What strategy would you use and explain why?
14x + 2y = 26
-14x - 6y = -50
elimination because the coefficients of x will cancel out.
Do the Check: Is the given point a solution to the system of equations?
Point: (2,6)
x + y = 8
3x - y = 0
What is Yes
How many solutions are there?
No Solutions
Solve the systems of equations using substitution:
-5x - 5y = 10
y = -4x -17
What is (-5, 3)
Solve the systems of equations using Elimination:
-3x - 5y = 2
3x + 5y = 7
No Solution
What strategy would you use and explain why?
-5x - 5y = 10
y = -4x -17
substitution because y is already solved for.
Do the Check: Is the given point a solution to the system of equations?
Point: (1/2, -2)
6x + 5y = -7
2x - 4y = -8
What is No
Solve Using Graphing or Substitution:
y = 5/3x + 2
y = -3
Solve the systems of equations using substitution:
y = -2x - 9
3x -6y = 9
What is (-3, -3)
Solve the systems of equations using Elimination:
-6x - 10y = 4
6x + 10y = -4
What is Infinitely Many
Is there 1 solution, No solution, or Infinite solutions for the system of linear equations below? AND JUSTIFY WHY
3x - y = 19
-3x + y = 10
What is no solutions because the slope is the same and the y-intercept isn't
What is a coefficient?
The number that is attached to the variable.
Solve the systems of linear equations by graphing or substitution:
4y = x - 8
-3x + 2y = 6

How you determine if lines are parallel.
What is the same slope, different y-intercepts
A line that has a slope of zero is this type of line.
What is a horizontal line
When using elimination you get the same slope and y-interecept
What is infinitely many solutions
3(x-5)=4x+12
