College Bound - Unit 2 Review

Front

Evaluate f(3).

Back

f(3) = 3

Front

Is this a function? Why or why not?

Back

Yes, because none of the domain numbers repeated.

Front

For the equation y + 1 = -3(x - 5), what is the slope?

Back

-3

Front

What does the slope represent in the graph of a burning candle's height?

Back

The change in the height of the candle each hour it is burning.

Front

Write the equation in point-slope form of the line that passes through (-2, -1) with slope m = -3.

Back

y + 1 = -3(x + 2)

Front

What is a function?

Back

A relation where each input (domain) has exactly one output (range).

Front

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

Back

y - y1 = m(x - x1), where m is the slope and (x1, y1) is a point on the line.

Front

How do you find the slope between two points (x1, y1) and (x2, y2)?

Back

Slope (m) = (y2 - y1) / (x2 - x1).

Front

What does a negative slope indicate about a line?

Back

The line decreases as it moves from left to right.

Front

What is the y-intercept of a line?

Back

The point where the line crosses the y-axis (x=0).
