Algebra S1 Final Review #3

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

What does the variable 'x' represent in the equation y = 8x + 4?

Back

In this equation, 'x' represents the number of oranges.

Front

How do you determine the slope of a line from its equation?

Back

The slope is the coefficient of x in the slope-intercept form (y = mx + b).

Front

What is a compound inequality?

Back

A compound inequality combines two inequalities, showing the range of values that satisfy both conditions.

Front

Write the compound inequality for a medium-sized apple with a diameter between 60mm and 90mm.

Back

60 ≤ d ≤ 90.

Front

What does T(55) = 7 indicate in a function?

Back

It indicates that when the input (speed) is 55, the output (amount of hydrogen left) is 7.

Front

What is the meaning of the y-intercept in a linear equation?

Back

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

Front

How can you identify a linear function from a set of data points?

Back

A linear function will show a constant rate of change, meaning the differences between y-values divided by the differences between x-values are constant.

Front

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

Back

The slope indicates the steepness of the line and the direction of the relationship between x and y.

Front

What does the equation y = 10x - 4 represent?

Back

It represents a linear function where the slope is 10 and the y-intercept is -4.
