Block 2 Slope-Intercept

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 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 the y-intercept in the equation y = 2x + 3?

Back

The y-intercept is 3, which is the point where the line crosses the y-axis.

Front

How does a positive slope affect the direction of a line?

Back

A positive slope means the line rises from left to right.

Front

How does a negative slope affect the direction of a line?

Back

A negative slope means the line falls from left to right.

Front

What transformation occurs when a function is shifted up by 2 units?

Back

The entire graph of the function moves up by 2 units.

Front

What transformation occurs when a function is reflected over the x-axis?

Back

The graph of the function is flipped over the x-axis.

Front

What does a slope of 0 indicate about a line?

Back

A slope of 0 indicates that the line is horizontal.

Front

What does an undefined slope indicate about a line?

Back

An undefined slope indicates that the line is vertical.

Front

If the equation of a line is y = -x + 2, what is the slope?

Back

The slope is -1.
