DMA 2 Review

Front

What is the standard form of the equation of a line represented by the slope-intercept form \(y = -\frac{2}{3}x + 4\)?

Back

The standard form is \(2x + 3y = 12\).

Front

Given the points (6, 165) and (11, 214), what is the equation for the line of fit for the weight of ladybugs based on their wingspan?

Back

The equation is \(y = 9.8x + 106.2\).

Front

What does the \(y\)-intercept of a savings account graph represent?

Back

It represents the initial amount in the savings account, which is $1200.

Front

How do you express 'Five times the sum of \(a\) and 2 is the same as \(b\)' in equation form?

Back

The equation is \(b = 5(a + 2)\).

Front

What is the average rate of change in miles per minute for a runner from 60 to 120 minutes if the distance traveled is \(0.093\) miles?

Back

The average rate of change is \(0.093\) miles per minute.

Front

What is the slope of the line represented by the equation \(y = -\frac{2}{3}x + 4\)?

Back

The slope is \(-\frac{2}{3}\).

Front

What does the slope of a line indicate in a real-world context?

Back

The slope indicates the rate of change of one variable with respect to another.

Front

How do you convert the equation \(y = mx + b\) to standard form?

Back

Rearrange to \(Ax + By = C\) where A, B, and C are integers.

Front

What is the meaning of the slope in the context of Keesha's savings account?

Back

The slope represents the amount Keesha adds to her savings account each month.

Front

What is the formula for calculating the average rate of change between two points \((x_1, y_1)\) and \((x_2, y_2)\)?

Back

The formula is \(\frac{y_2 - y_1}{x_2 - x_1}\).
