4.4a QZ

Front

What is the slope in the equation y=mx+b?

Back

The slope (m) represents the rate of change of y with respect to x.

Front

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

Back

The y-intercept (b) is the value of y when x=0, indicating where the line crosses the y-axis.

Front

What is the slope of the line represented by the equation y=2x + 3?

Back

The slope is 2.

Front

Write the equation of a line with a slope of -3 and a y-intercept of 3.

Back

y = -3x + 3.

Front

Which equation represents a line with a positive slope?

Back

y = 3x + 2.

Front

What is the equation of a line that passes through the point (0, -3)?

Back

y = mx - 3, where m is the slope.

Front

How do you determine the slope from two points (x1, y1) and (x2, y2)?

Back

Slope (m) = (y2 - y1) / (x2 - x1).

Front

What does it mean if a line has a slope of 0?

Back

The line is horizontal and does not rise or fall.

Front

What does it mean if a line has an undefined slope?

Back

The line is vertical and cannot be expressed as y = mx + b.

Front

How can you identify the slope from a graph?

Back

The slope is the rise over run between two points on the line.
