Graphing Slope Intercept Form Check

Front

What does the 'b' represent in the slope-intercept form equation y = mx + b?

Back

Y-intercept, which is the point where the line crosses the y-axis.

Front

What does the 'm' represent in the slope-intercept form equation y = mx + b?

Back

Slope, which indicates the steepness and direction of the line.

Front

How do you identify the y-intercept from the equation y = mx + b?

Back

The y-intercept is the value of 'b' in the equation.

Front

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

Back

The slope is 3, indicating that for every unit increase in x, y increases by 3.

Front

What does a positive slope indicate about a line on a graph?

Back

A positive slope indicates that the line rises from left to right.

Front

What does a negative slope indicate about a line on a graph?

Back

A negative slope indicates that the line falls from left to right.

Front

How can you determine the slope from two points on a line (x1, y1) and (x2, y2)?

Back

Slope (m) can be calculated using the formula m = (y2 - y1) / (x2 - x1).

Front

What is the general form of the slope-intercept equation?

Back

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

Front

If a line has a slope of 0, what does this indicate about the line?

Back

A slope of 0 indicates a horizontal line.

Front

If a line has an undefined slope, what does this indicate about the line?

Back

An undefined slope indicates a vertical line.
