Definitions
The quadrant in which the solution to the following system lies:
y = x + 4
y = 2x + 5
What is II
If a system has a solution, it looks like this.
What is 2 lines that cross?
This is the slope of a horizontal line.
What is 0?
Two lines that intersect at a point on the graph will have this many solutions.
What is one?
y = 3x - 2
y = -x - 2
If a system has no solution, the graph looks like this.
What is parallel lines?
This is the y-intercept of a line going through the origin.
What is 0?
Parallel lines will have this......
What is no solution?
The solution to an equation or system of equations tells you this.
Where the lines intersect?
y = -3
x = 5
If a system has infinite solutions, this is what the graph looks like.
What is the same line?
This is the slope and y-intercept for the following equation.
y = 3x
What is slope = 3 & y-intercept=0
A system of equations that has a parabola and a line could have this many solutions. (Give every possible answer.)
What is 0, 1 or 2?
In the general linear equation, y=mx+b, the b value tells you this.
What is the y-intercept?
y = (1/3)x - 3
y = 2x - 8
If lines are parallel, then this is the same in their equations.
What is the slope?
This is the slope for a line passing through these 2 points, (-4, -8) & (3, 4).
What is 12/7 or 1 5/7?
A system of equations that has different slopes, but the same y-intercept will have this many solutions.
What is 1?
In the general linear equation, y=mx+b, this letter stands for the slope.
What is m?
y = 3x + 2
y = 3x - 2
If lines are perpendicular then their slopes are this.
What are opposite reciprocals?
This is the equation for the line that goes through these 2 points, (3, 7) and (-2, 10).
What is y = -3/5x +94/5?
y = -1/2 x + 9 and it's perpendicular have a solution of (0,9). This is the equation for the other line.
What is y=2x + 9?
