Slope & Slope-Intercept

Front

Slope is known as

Back

rise/run

Front

Back

Slope: -2, Y-intercept: -4

Front

Find the slope of the line represented by the points (1, 2) and (4, 5).

Back

Slope = (5-2)/(4-1) = 3/3 = 1

Front

What is the slope of a horizontal line?

Back

0

Front

What is the slope of a vertical line?

Back

Undefined

Front

Find the slope of the line using rise/run: If a line rises 4 units and runs 2 units, what is the slope?

Back

Slope = rise/run = 4/2 = 2

Front

What does a positive slope indicate about a line?

Back

The line rises from left to right.

Front

What does a negative slope indicate about a line?

Back

The line falls from left to right.

Front

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

Back

Front

If the slope of a line is -5/3, what does this mean in terms of rise and run?

Back

For every 5 units the line falls (rise = -5), it runs 3 units to the right.
