Front

What is the X-INTERCEPT of a graph?

Back

The X-INTERCEPT is the point where the graph crosses the X-axis, meaning the value of Y is 0.

Front

What is the RANGE of a function?

Back

The RANGE is the set of all possible output values (Y-values) of a function.

Front

Write the equation in point-slope form of the line that passes through the point (4, -7) and has a slope of -1/4.

Back

y + 7 = -1/4(x - 4)

Front

What does it mean when we say y ≤ 1 in terms of RANGE?

Back

It means that the output values (Y-values) of the function can be 1 or any value less than 1.

Front

How do you find the slope of a line given two points?

Back

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

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

How do you convert from point-slope form to slope-intercept form?

Back

You can convert by solving for y in the point-slope equation.

Front

What is the significance of the y-intercept in a graph?

Back

The y-intercept is the point where the graph crosses the Y-axis, indicating the value of Y when X is 0.

Front

What does it mean for a function to be increasing?

Back

A function is increasing if, as X increases, Y also increases.

Front

What does it mean for a function to be decreasing?

Back

A function is decreasing if, as X increases, Y decreases.
