What is a scale drawing?

Back

A scale drawing is a representation of an object or a space that maintains the proportions of the original while being resized.

Front

How do you find the measurement of a variable in a scale drawing?

Back

To find the measurement of a variable in a scale drawing, set up a proportion based on the known measurements of the original and the drawing.

If Justin can type 408 words in 4 minutes, how do you calculate his typing speed per minute?

Back

Divide the total words by the total minutes: 408 words ÷ 4 minutes = 102 words per minute.

Front

What are x and y intercepts in a linear equation?

Back

The x-intercept is the point where the line crosses the x-axis (y=0), and the y-intercept is where it crosses the y-axis (x=0).

Front

How do you find the x-intercept of the equation 4x - 5y = 40?

Back

Set y = 0 and solve for x: 4x = 40, so x = 10.

Front

How do you find the y-intercept of the equation 4x - 5y = 40?

Back

Set x = 0 and solve for y: -5y = 40, so y = -8.

Front

What is a proportion?

Back

A proportion is an equation that states that two ratios are equivalent.

Front

How can you determine if two ratios form a proportion?

Back

Two ratios form a proportion if their cross products are equal.

Front

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

Back

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

Front

Convert the equation 8x + 4y = 16 to slope-intercept form.

Back

y = -2x + 4.
