Slope Intercept Form & Writing Equations Test period 9

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 = 3/2x + 3?

Back

The slope is 3/2.

Front

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

Back

The y-intercept (b) represents the point where the line crosses the y-axis.

Front

What is the y-intercept of the equation y = 3/2x + 3?

Back

The y-intercept is (0, 3).

Front

What is the slope of a line that rises 4 units for every 2 units it runs?

Back

The slope is 2 (4/2 = 2).

Front

What does 'm' represent in the equation y = mx + b?

Back

The 'm' represents the slope of the line.

Front

What is the slope of a horizontal line?

Back

The slope of a horizontal line is 0.

Front

What is the slope of a vertical line?

Back

The slope of a vertical line is undefined.

Front

If a line has a slope of -1, what does that indicate about its direction?

Back

A slope of -1 indicates that the line descends from left to right.

Front

Can the graph of a linear function be shaped like a 'u'?

Back

No, the graph of a linear function is always a straight line.
