Systems and Inequalities CB

Front

What indicates that an inequality will have a solid line?

Back

The symbol has a line under it (e.g., ≤ or ≥).

Front

Solve the system of equations: y = 2x + 1 and y = 4x - 1.

Back

(1, 3)

Front

For the equation y - 3 = 2(x + 4), what is the slope and what point does it contain?

Back

The slope is 2 and it contains the point (-4, 3).

Front

What symbol represents 'less than'?

Back

<

Front

Which inequalities match the graph: y > 2x - 4 and y < 2?

Back

y > 2x - 4 and y < 2.

Front

What does the symbol '>' mean in inequalities?

Back

It means 'greater than'.

Front

What is the solution to the inequality y < 3x + 2 when x = 1?

Back

y < 5.

Front

How do you graph the inequality y ≥ -2x + 3?

Back

Graph the line -2x + 3 with a solid line and shade above it.

Front

What is the difference between a solid line and a dashed line in graphing inequalities?

Back

A solid line indicates that points on the line are included (≥ or ≤), while a dashed line indicates they are not (> or <).

Front

What does the symbol '≤' represent?

Back

It represents 'less than or equal to'.
