identify the slope
m, always given as a fraction
identify the y-intercept
b = where the line crosses the y-axis
a solid line
What type of line do you use to graph an inequalitiy that is greater than or equal to or less than or equal to
a dashed line
What type of line do you use to graph an inequalitiy that is greater than or less than
above the line
Where do you shade for an inequality that is greater than
below the line
Where do you shade for an inequality that is less than
It is where the shadings over lap.
How do you identify the solution to a system of inequalities?
When do you flip your symbol?
When you multiply or divide by a negative
Would a number that falls on a dashed line be considered a solution?
No, a line would be a solid line in order to consider it a solution. The solid line is "equal to" a dashed line is just greater than or less than
