Algebra 1 warm up 12/11 & 12/12

Front

What is the graph of the equation x = -4?

Back

A vertical line that crosses the x-axis at -4.

Front

What is the slope of the line represented by the equation y = 4x - 1?

Back

The slope is 4, indicating the line rises 4 units for every 1 unit it moves to the right.

Front

What is the equation of a line with a zero slope that goes through the point (6, 7)?

Back

y = 7, which represents a horizontal line.

Front

What is the equation of a line with an undefined slope that goes through the point (-3, 5)?

Back

x = -3, which represents a vertical line.

Front

What does the slope-intercept form of a line look like?

Back

It is written as y = mx + b, where m is the slope and b is the y-intercept.

Front

How do you find the slope of a line given two points (x1, y1) and (x2, y2)?

Back

The slope m is calculated as m = (y2 - y1) / (x2 - x1).

Front

What does a positive slope indicate about a line?

Back

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

Front

What does a negative slope indicate about a line?

Back

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

Front

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

Back

The y-intercept is 1, which is the point where the line crosses the y-axis.

Front

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

Back

A slope of zero indicates a horizontal line.
