Review of Math 8 - End of Year Review

Front

What is a reflection in geometry?

Back

A reflection is a transformation that flips a figure over a line, creating a mirror image.

Front

What does the slope of a line represent?

Back

The slope represents the rate of change of the y-coordinate with respect to the x-coordinate in a linear equation.

Front

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

Back

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

Front

What is the slope of the line represented by the equation y = 2x + 3?

Back

The slope is 2.

Front

What is the equation of a line in slope-intercept form?

Back

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

Front

How do you write an equation for a real-world scenario involving costs?

Back

Identify fixed costs and variable costs, then express the total cost as a function of the variable.

Front

What is the y-intercept in the equation y = 15x + 25?

Back

The y-intercept is 25.

Front

What does it mean for an equation to be linear?

Back

A linear equation represents a straight line when graphed and has the form y = mx + b.

Front

What is the formula for calculating the cost of renting a snowboard for x hours if the cost is $15 per hour plus a $25 rental fee?

Back

The equation is y = 15x + 25.

Front

What is the slope of the line that passes through the points (2, 3) and (4, 6)?

Back

The slope is 3/2.
