Ms. Saxon.......Question? 

Slope-intercept

100

What is the slope-intercept form?

y=mx+b

200

What does each variable in the equation mean?

( m and b)

y=mx+b

m is slope

b is the y-intercept

300

What is the slope formula from two points?

(y₂-y₁) / (x₂ - x₁)

400

Write in slope intercept form

(0, 4) m=-2

y= -2x +4

500

Find the slope

(2,5) , (-4,13)

slope: -4/3

Standard Form

100

What is the standard form?

Ax+By=C

200

Is the x-axis horizontal or vertical?

Horizontal 

300

3x-7y=-18

(-6,0)

400

Where does Ms.Saxon's boyfriend come from?

Canada

500

2x+3y=12

Put in slope-intercept form 

y=-2/3x+4

Point-slope

100

What is the point-slope form?

y-y₁=m(x-x₁)

200

What is the ordered pair of the equation?

y - 3 = 7/8 (x+2)

(-2 , 3)

300

y+0 = -1/2(x-5)

What is the slope?

-1/2

400

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

what is the point?

(5,-4)

500

Which correlation coefficient indicates a moderate negative correlation between an independent variable x and the dependent variable y?

a) -0.05                                  b) -0.40

c)  -0.83                                 d)  -0.99

C

Converting

100

Convert to standard form

y=-2x + 5

2x + y = 5

200

Convert to slope intercept

2x+3y=-6

y = -2/3x -2

300

Convert to slope intercept

y-3 = 5(x-1)

y= 5x-2

400

At which point do the graphs of 2x - y = 1

and 3x + 2y = 12 intersect?

(2,3)

500

Which is the slope of a line perpendicular to a line that passes through (0,-3) and (5,0)

A) -5/3

B) -3/5

C)  3/5

-5/3
