How do you determine if a point is a solution to a linear inequality?

• Graph the point and see if it falls on the line

• Count the number of vowels in the point's coordinates

• Ask a friend if they think the point is a solution

• Substitute the point's coordinates into the inequality and check if it holds true

What is the solution to the system of linear inequalities: y < 2x - 1 and y > -x + 3?

• The solution is the region above the line y = 2x - 1

• The solution is the region to the left of the line y = 2x - 1

• The solution is the region between the two lines y < 2x - 1 and y > -x + 3.

• The solution is the region below the line y = -x + 3

When graphing a linear inequality, how do you determine if the line should be solid or dashed?

• Solid for even numbers, dashed for odd numbers

• Solid for addition, dashed for subtraction

• Solid or dashed based on the presence of the equal sign

• Solid for positive slope, dashed for negative slope

What is the solution to the system of linear inequalities: 3x - 2y < 6 and 2x + y > 4?

• The solution is a single point on the graph.

• The solution is the region where the two shaded areas do not overlap.
