A16 - Graphing Slope-Intercept Form

Front

What is the slope of a line that rises from left to right?

Back

Positive

Front

What is the slope of a line that falls from left to right?

Back

Negative

Front

What does an undefined slope indicate about a line?

Back

The line is vertical.

Front

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

Back

The value of b, where the line crosses the y-axis.

Front

How do you identify the slope from the equation y = mx + b?

Back

The slope is represented by m.

Front

What is the slope of a horizontal line?

Back

Zero.

Front

Write the slope-intercept form of a line with a slope of 2 and a y-intercept of -3.

Back

y = 2x - 3

Front

What is the first step in graphing a line in slope-intercept form?

Back

Plot the y-intercept.

Front

If a line has a slope of 1/2, what does this mean in terms of rise and run?

Back

For every 2 units you move right (run), you move up 1 unit (rise).

Front

What is the equation of a line that passes through the point (0, 4) with a slope of -1?

Back

y = -1x + 4
