FOA End of the Year Review Practice 2

Front

What is the inequality represented by the graph with a slope of -3 and a y-intercept of 4?

Back

y ≥ -3x + 4

Front

Which inequality function matches a graph with a slope of 1/3 and a y-intercept of 5?

Back

y ≥ \frac{1}{3}x + 5

Front

What does a negative rate of change indicate in a graph?

Back

It indicates that as the x-value increases, the y-value decreases.

Front

What is the factored form of the expression x² - 25?

Back

(x + 5)(x - 5)

Front

How can you determine if a relation is a function?

Back

A relation is a function if each input (x-value) has exactly one output (y-value).

Front

What is the slope of a line that decreases at a rate of 15 feet per minute?

Back

-15 feet per minute

Front

What is the definition of a linear inequality?

Back

A linear inequality is an inequality that involves a linear function and can be expressed in the form ax + by < c, ax + by > c, ax + by ≤ c, or ax + by ≥ c.

Front

What does the symbol '≥' represent in inequalities?

Back

It means 'greater than or equal to'.

Front

What is the solution to the inequality 2x - 3 < 5?

Back

x < 4.

Front

What is the graphical representation of the inequality y < 2x + 3?

Back

The area below the line y = 2x + 3, not including the line itself.
