300

Give the slope of the line that passes through these points. 

(-4, -4)  (4, 2)

m = 6/8

m = 3/4

400

Find the slope of the two given points:

(-3, 4) and (1, 7)

m = 3/4

500

Find the slope of the given points and what is the specific word that describes this slope?

(4, 10)  (4, 14)

slope = 4/0

The slope is called undefined because it is a vertical line. 

4.4 Slope Intercept Form

y = 2/3x + 3

200

Give what the slope and the y-intercept are of the equation. 

y - 5 = 3x

m = 3

y intercept = 5

300

Write in slope intercept form given the points.

(-3,9)  (0,6)  

y = -x + 6

400

Write in slope intercept form given the points.

(-2,-5)  (0,6)

y = 11/2x + 6

m =11/2 

y intercept = 6

500

Change to slope intercept form.

4x + 2y = -12

y = -2x - 6

4.5 Standard Form

100

Graph the equation 4x + 2y = 8

x intercept = 2

y intercept = 4

200

Find the x and y intercept of the equation

x + 5y = 10

x intercept = 10

y intercept = 2

300

Find the x and y intercept of the equation.

2x + 3y = 6

x intercept = 3

y intercept = 2

400

2x - y = 8

x intercept = 4

y intercept = -8

500

Graph the equation below:

-1/2x + 2y = 6

m = -3/4

y intercept = 3

Two points should be located:

(0, 3) and (4,0)

200

Find the equation of the graph that passes through points:

(0,2) and (2, -3)

y = -5/2x + 2

300

Graph the equation

y = 7/5x - 3

Use graphing/board or graphing paper for answers

rise = 7

run = 5

y intercept = -3

400

Graph the linear equation:

y - 4 = -2/7x

Two points could be:

(0,4) and (7, 2)

y = 5/3x - 3

Miscellaneous

100

Put into point-slope form:

(4,2); m = 1/5

y - 2 = 1/5(x - 4)

200

Write the equation in point slope form given the two points:

(2,3)  (5, 9)

y - 3 = 6/3(x - 2)

or 

y - 3 = 2(x - 2)

300

Write the equation in point slope form given the two points:

(-3,4)  (1, -3)

y - 4 = -7/4(x - (-3))

or

y - 4 = -7/4(x + 3)
