-4

200

Is 4 the Slope of 2-1/1-2?

No 

300

How do you get the slope of these points?

(5,3) (4,7)

You subtract y1 and y2 and then subtract x1 and x2.

2

300

Change to slope-intercept

8x+8y=4

y=-x+1/2

400

describe the parts?

y=mx+b

x is the Slope

b is the Y-Intercept

500

Turn into slope-intercept.

8x+2y=6

y=-4x+3

Point Slope

100

Turn this into Point-Slope Form

(1,2) m=3

(y-2)=3(x-1)

200

Put this into Slope-Intercept Form.

(y-5)=6(x-2)

y=6x+-7

300

Define all of the parts of Point-Slope Form.

Y1=your Y 

X1=your X

400

Put this into Point-Slope

(5,-3)  M=7

(y--3)=7(x+5) 

or

(y+3)=7(x+5)

500

Put this into Point-Slope

(16,26)   M=38

(y-26)=38(x+16)

Standard form

100

Turn this into Slope-Intercept Form

2x+1y=4

y=-2x+4

200

Is this in Standard Form?

-1/2x+4y=8 

If it is not in Standard Form what is wrong with it?

It can't be negative, a fraction, and the G.C.F. has to be 1

300

Change this into Slope-Intercept Form

1x+4y+9

y=1/4x+2.25

400

Solve for Y

6x+3y=3
