Graphing
Where do you find the solution to a system of equations on a graph?
What is "the point where the two lines cross/intersect"?
Solve the system using substitution.
y = 1
y = 3x + 4
When do you add the two equations?
What is "when the signs are opposite?"
What is the first step in graphing a linear inequality?
What is "plot the y-intercept?"
In the equation y = 3x + 4, what is the slope?
What is "3?"
How many solutions would two parallel lines have?
What is "zero/none"?
Solve the system using substitution:
x = 2
y = -2x + 1
What is (2, -3)?
When do you subtract the two equations?
What is "when the signs are the same?"
When will your line be dotted?
What is "when the inequality is just 'less than' or just 'greater than'?"
Solve for x.
3x + 3 < 9
What is "x < 2"?
Graph the system of equations:
y = 2x + 2
y = x - 1
Find the solution.
What is (-3, -4)?
Solve the system using substitution:
y = 2x
y = 3x - 1
What is (1, 2)?
Solve the system using elimination:
2x + 3y = 15
x - 3y = 3
What is (6, 1)?
How do you know which side of the graph to shade?
What is "pick a test point, if it works, shade the side the test point was on, if it doesn't work, shade the other side"?
Which ordered pair is located 2 units to the left of the ordered pair (9, -2)?
What is "(9, -4)"?
Graph the system of equations:
y = -4/3x + 1
x = 3
What is the solution?
What is (3, -3)?
Solve the system using substitution:
y = -x + 1
y = 3x + 5
What is (-1, 2)?
Solve the system using elimination:
2x + 3y = 20
-2x + y = 4
What is (1, 6)?
Which side of the graph (top or bottom) would you shade for the inequality y > -1/2x - 3?
What is "top?"
What is "5"?
Graph the system of equations:
y = 5/2x + 3
y = -x - 3
What is the solution?
What is (2, 1)?
Solve the system using substitution:
y = 4x - 6
y = 2x + 4
What is (5, 14)?
Solve the system using elimination:
6x - 6y = 6
8x - 6y = 20
What is (7, 6)?
Given the inequality, y < -3/2x - 4, after you graph the y-intercept, what would be the second point that you graph?
What is "(-7, 2)" or "(-2, 1)"?
What is...
2 + 2
????
What is "4"?
