GMAS Review - 8th Grade Math

Front

What is the equation for a dog walker who earns $10 plus $3 per dog?

Back

y = 3x + 10

Front

What does the initial value of a line represent?

Back

The initial value is the y-intercept of the line, indicating the starting point of the function when x = 0.

Front

How do you solve for H in the formula for the volume of a prism, V = LWH?

Back

H = \frac{V}{LW}

Front

What does the rate of change of a line indicate?

Back

The rate of change indicates how much y changes for a unit change in x, represented by the slope of the line.

Front

Which equation has the smallest rate of change: y=3x + 3, y=-3x + 3, y=(1/3)(x), y=3x?

Back

y = -3x + 3 has the smallest rate of change.

Front

What is the formula for the volume of a rectangular prism?

Back

V = LWH, where L is length, W is width, and H is height.

Front

What is the meaning of the slope in a linear equation?

Back

The slope represents the rate of change of the dependent variable with respect to the independent variable.

Front

How do you find the y-intercept of a linear equation?

Back

Set x = 0 in the equation and solve for y.

Front

What is the significance of the coefficients in a linear equation?

Back

Coefficients determine the steepness and direction of the line.

Front

What does it mean if a line has a positive slope?

Back

A positive slope indicates that as x increases, y also increases.
