Two or more linear equations with the same variables is known as......
System of Linear Equations
y = x + 4
y = 2x + 5
The solution to the system:
x = 4y
2x + 3y = 22
What is (8, 2)
When the slopes are the same in a system of linear equations, what does this mean about a solution?
No solution, parallel.
How is an ordered pair written?
x, y
Mrs. Kraus's first name
Sarah
y = 3x - 2
y = -x - 2
y = x - 2
3x - y = 16
When the slopes are ___________, a system of linear equations has one solution.
different
Is 3x + 5y = -2 a linear function?
Yes
The answer to an equation or system of equations.
What is a solution set or solution.
y = -3
x = 5
y = 3x - 1
7x + 2y = 37
If the two equations in a system have the same slope and y-intercept, what does this tell you about the solution to the system?
The lines are the same, infinitely many solutions
The slope of a vertical line
Undefined!!!!!!!!!
y = (1/3)x - 3
2x - y = 8
3s - 2t = 4
t = 2s - 1
2x + 4y = 8
Subtract 2x from both sides
What value will be substituted for x in the following system?
y = 2x + 1
x = 5y
5y
The ratio of rise to run
What is slope
y - 3x = 3
y = 3x - 2
t + u = 12
t = (1/3)u
Put the following equation in slope-intercept form:
3x - y = 12
y = 3x - 12 or y = 3x + -12
True or false: A function that does not have a constant rate of change would be a linear function.
False
