Final Jeopardy

Identify the slope given the following points:

(5, 6) and (-7, 8)

- 1/6

Identify the slope given the following points:

(-1, 4) and (5, 10)

What number represents the slope in the following equation?

y = -10x + 12

What number represents the

y-intercept in the following equation?

y = 6x - 22

What is the y-intercept in the following equation?

2x + 4y = 8

True or False:

The equation - y = 2x + 5 is in slope-intercept form.

False, y cannot be negative

True or False:

In the equation y = mx + b, the m represents the y-intercept and the b represents the slope.

False

Convert the following equation to

slope-intercept form: 6x + 3y = 9

y = -2x + 3

Convert the follow equation to slope-intercept form: -4x + 2y = - 12

y = 2x – 6

or

y = 2x + -6

Convert the following equation to slope-intercept form:

5x – 2y = - 10

y = 2.5x + 5

Write an equation for a line in slope-intercept form with a slope of 6 and a y-intercept of -7.

y = 6x – 7

or

y = 6x + -7

.

Write an equation for a line in slope-intercept form that has a slope of 2 and an x-intercept of 3.

0 = 2 (3) + b

b = -6

y = 2x – 6 or y = 2x + -6

Write an equation for a line in slope-intercept form that passes through the point (4, 5) and has a slope of 3.

.

5 = 3 (4) + b

b = -7

y = 3x – 7 or y = 3x + -7

Write an equation for a line in slope-intercept form that passes through the points

(6, 7) and (8, 21)

(21-7) / (8 – 6) = 14/2 = 7 = slope

7 = 6(7) + b

-35 = b

y = 7x – 35 or y = 7x + -35

Write an equation for a line in slope-intercept form that passes through the points

(5, 6) and (7, -6)

(-6 – 6) / (7 - 5) = -12/2 = -6 = slope

6 = -6(5) + b

6 = -30 + b

36 = b y = -6x + 36

True or false:

The following lines are parallel to one another.

y = 4x + 5

y = 4x - 6

TRUE

Same Slope!

True or False:

The following lines are perpendicular to one another:

y = -0.5x + 2

y = 2x + 4

True

Slopes are opposite, reciprocals!

Give a line parallel to the following:

y = -1/3x + 4

Variety! Slope must be the same.

Give a line perpendicular to the following:

y = 2/5x + 5

Variety! Slope must be opposite reciprocal, so -2.5

Find a line perpendicular to the following:

4x + 2y = 10

y = 1/2x + 5 would be the converted form, so the perpendicular line would need to have a slope of 2x.

True or False:

A line of best fit should have about the same number of points above and below the line.

• True or False:

• When creating a line of best fit, you should connect all of the points with a line.

False, not making a line graph.

True or False:

We can identify the y-intercept on a graph by seeing where the line crosses the

y-axis.

True, when x=0, what is y??

True or False

The x-intercept can be found on a graph by identifying where the line crosses the x-axis.

True, when y=0, what is x???

The Smith family recently adopted a new puppy. At 10 weeks old, the puppy weighed 7 pounds. At 19 weeks, the puppy weighed 16 pounds. Give the two ordered pairs and write the equation in slope-intercept form.

(10, 7) AND (19, 16)

y = 1x + -3
