Point-Slope Form

100

(2, 7) 

m = -4 

y – 7 = -4(x – 2)

200

(-6, -2)  

m = 3 

y + 2 = 3(x + 6)

300

(10, 5) 

m = -3 

y – 5 = -3(x – 10)

400

(7, -6) 

m = 1/2 

y + 6 = 1/2(x - 7) 

500

(-8, 2) 

m = -3/4 

y - 2 = -3/4 (x + 8) 

Find y

100

y - x = -6

x = 4 

y = -2

200

-2y + 10x = 46

x = 6

300

2x + 4y = 24

x = 2

y = 5 

400

3x + 6y = 33

x = 9

y = 1

500

2x +2y = -2

x = 2

y = -3
