Patterns and Slope

Find the slope given these points:

(2,-4) and (3,1)

• 5

• -3

• 3

• -5

In the equation y=mx+b, what does the m represent?

• slope

• y-intercept

• linear

• point-slope

Parallel lines have __________ slopes

• Equal

• Opposite

• Negative Reciprocal

• Total

Answer explanation

Equal means the same. Parallel lines have the same slope.

Slopes of perpendicular lines are...

• negative reciprocals.

• opposites.

• identical.

• always 7.

What is the slope of a line perpendicular to a line with slope ^-6/₅ ?

• ^-6/₅

• ^-5/6

• ⁵/₆

• ^-4/₃

Answer explanation

perpendicular lines have Negative Reciprocal slopes.

Which two lines are parallel?

• Line A and Line B

• Line A and Line C

• Line B and Line C

• None

Answer explanation

Lines A and B have the same slope (up/right).

Which two lines are perpendicular?

• Line A and Line C

• Line B and Line C

• Line A and Line B

• none

Answer explanation

The slope of Line A = -5/4 and

The slope of Line B = 4/5.

They are negative reciprocals.

Suppose that a bike rents for $4 plus $1.50 per hour. Write an equation in slope-intercept form that models this situation.

• y = 4x + 1.50

• y = 1.50x + 4

How many tiles would Figure 0 contain?

• 1

• 4

• 7

• 10

What is the rule of the pattern based on the growth and the number of tiles in Figure 0?

• y=3x+4

• y=3x

• y=1x+3

• y= 3x+1
