What are the two things we need to know in order to write a linear equation?

slope and y-intercept

100

Write an equation for a line that goes through (0, -2) and (3, 0)

y = 2/3x - 2

100

Evaluate:

-2 - 5

-7

200
Identify the slope of the following equation. y = 2x + 3
slope is 2
200
When graphing linear equations, where do we begin?
We begin at the y-intercept.
200

Given that the slope is 3 and the y-intercept is -6, write the equation of the line.

y=3x-6

200

Write an equation for a line with the following two points. Find the slope and y intercept. (15, -10) (5, 10)

slope = -2 y intercept = 20

y = -2x + 20

Which is hotter... the sun or a lightening bolt?

Lightening Bolt (by about 5 times!!)

300
Name three ways to describe slope.
Possible answers: rate of change rise over run y - y x - x slope = m in y = mx + b
300
Graph the following equation. Include at least 3 points. y = 1/3x + 4
Graph should start with the point at (0, 4) Movement should be 1 up and 3 to the right continuing to another point. Movement could also be 1 down and 3 to the left.

Find the line that has a slope of -1 and through the point (3, -2) 

y = -x + 1

300

Write an equation of a line that passes through (8, -24) and (-1, 3).

y = -3x - 1

~2000

400
Find the slope of the line that includes the following points. (4, -5) (-4, 5)
-10/8 which simplifies to -5/4
400
Graph the following equation. Include at least three points. y = -2
Graph should begin with a point on the y-axis at -2. A horizontal line should be drawn through -2 extending on both sides of the y-axis.
400
Write the equation of a line that has a slope of 5 and goes through the point (-1,-3)

y = 5x + 2

400

Write the equation of the line that passes through (-4, 4) and (7, 9)

y=5/11x+5.8

Purple

500
Find the slope of the line that includes the following points. (-12, -9) (-3, -3)
-6/-9 = 6/9 = 2/3
500
Make a table of values with at least 4 ordered pairs for the following equation. y = 1/2x -5 Then plot the ordered pairs. Draw a line through the points.
Table should list four numbers chosen for x and then solved by multiplying by 1/2 and subtracting 5. If x is 2 then If x is 4 then 1/2(2) = 1 - 5 1/2(4) = 2 - 5 then y = -4 then y = -3
