Alg 1 Unit 5 Flashcard Review

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 identify the slope from the equation y = ⅖x + 2?

Back

The slope is ⅖.

Front

What does the y-intercept represent in the equation y = ⅖x + 2?

Back

The y-intercept is the point where the line crosses the y-axis, which is 2 in this case.

Front

What is the equation of the line with a slope of -4/5 and a y-intercept of 3?

Back

The equation is y = -4/5x + 3.

Front

How do you determine the graph of y = ⅔x - 1?

Back

The graph has a slope of ⅔ and a y-intercept of -1.

Front

What is the slope of the line represented by y = -¾x + 1?

Back

The slope is -¾.

Front

How can you tell if a graph represents a positive slope?

Back

A graph has a positive slope if it rises from left to right.

Front

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

Back

The slope indicates the rate of change of y with respect to x.

Front

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

Back

A slope of 0 means the line is horizontal and does not change in y as x changes.

Front

How do you find the y-intercept from the equation y = 4x?

Back

The y-intercept is 0, as the equation can be rewritten as y = 4x + 0.
