Front

What is the solution to the inequality 2x + 4 ≥ 14?

Back

x ≥ 5

Front

Which points satisfy the inequality y < 2x - 3?

Back

A. {(3, 3), (-1, -11), (0, -8), (5, 0)}

Front

What rule generates the values in the table if y = 7x + 23?

Back

y = 7x + 23

Front

How do you represent the inequality y < 1/2x - 1 graphically?

Back

Graph B correctly represents the inequality.

Front

If y varies directly as x and y = 8 when x = 3, what is y when x = 9?

Back

y = 24

Front

What does it mean for y to vary directly as x?

Back

It means y = kx for some constant k.

Front

How do you solve the inequality 2x + 4 ≥ 14?

Back

Subtract 4 from both sides: 2x ≥ 10, then divide by 2: x ≥ 5.

Front

What is the graphical representation of y < mx + b?

Back

The area below the line y = mx + b.

Front

What is the slope-intercept form of a linear equation?

Back

y = mx + b, where m is the slope and b is the y-intercept.

Front

How do you determine if a point (x, y) satisfies an inequality?

Back

Substitute x and y into the inequality and check if it holds true.
