2nd District Assessment Review - 7th Advanced Math 24-25

Front

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

Back

The equation of a line in slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.

Front

How do you find the slope of a line given two points (x1, y1) and (x2, y2)?

Back

The slope (m) is calculated using the formula m = (y2 - y1) / (x2 - x1).

Front

What does the slope of a line represent?

Back

The slope represents the rate of change of y with respect to x; it indicates how steep the line is.

Front

What is a y-intercept?

Back

The y-intercept is the point where the line crosses the y-axis, represented by the value of y when x = 0.

Front

What is the difference between a function and not a function?

Back

A function is a relation where each input (x) has exactly one output (y). A relation is not a function if an input has multiple outputs.

Front

If a car travels at a constant speed of 60 miles per hour, how far will it travel in 3 hours?

Back

180 miles.

Front

What is the formula to calculate distance when speed and time are known?

Back

Distance = Speed × Time.

Front

What does the equation y = 3x - 6 represent?

Back

It represents a linear function where the slope is 3 and the y-intercept is -6.

Front

How can you determine if a graph represents a function?

Back

Use the vertical line test: if a vertical line intersects the graph at more than one point, it is not a function.

Front

What is the slope of the line represented by the equation y = -1/4x - 1.5?

Back

The slope is -1/4.
