Is (x,y) a solution to the System of Inequalities?
100
What inequality symbol would you use for the words "at least?"
100
DASHED!
100
What are the two things you need in order to graph a linear equation?
Slope and the y-intercept
100
Graph the system of inequalities
y > x + 1
y > -x
100
Is the point a solution to the system?
No! The point lies on the DASHED line, so you cannot include it in the solution!
200
What inequality symbol would you use for the words "at most?"
200
ABOVE!
200
The line y = -2x - 3 has what y-intercept?
What is -3?
200
200
Is the point a solution to the system?
Yes! This point lies in the shaded region.

A linear equation defined by m = 2/3 and b = 6 is what equation written in slope intercept form?
What is y = 2/3 x + 6?
300
300
Is the point a solution to the system?
Yes! This point lies on the SOLID line, so it IS a part of the solution!
(Hint: Each tick mark on the graph goes up by 2s!)

Is (0,0) a solution to the system of inequalities below?
No! The point (0,0) lies outside of the shaded region.

Answer: D
(Hint: Plug in "x" and "y" for each point to
see which ordered pair makes the inequalities true statements!)
