Unit 3 Part 2Test Review

Front

What happens to the graph of y = x when the equation changes to y = 1/2x + 11?

Back

The graph becomes less steep and shifts up 11 units.

Front

What is the slope-intercept form of the line represented by the graph?

Back

y = -x + 2

Front

Which equation represents the parent function shifted down two units?

Back

y = x - 2

Front

If a holiday meal costs $12.50 per person plus a delivery fee of $30, what is the equation for the total cost for x people?

Back

y = 30 + 12.5x

Front

Does the equation y = 4 represent a horizontal or vertical line?

Back

Horizontal

Front

What is the slope of the line represented by the equation y = 3x + 5?

Back

The slope is 3.

Front

How does the graph of y = -2x + 4 compare to the parent function y = x?

Back

It is steeper and reflected over the x-axis.

Front

What does the y-intercept represent in the equation y = mx + b?

Back

The y-intercept is the value of y when x = 0.

Front

What is the effect of adding a constant to the equation y = x?

Back

It shifts the graph vertically.

Front

What is the equation of a line with a slope of 0?

Back

y = b, where b is a constant.
