Standard to Slope-Intercept

100

4x + 2y = 6

y = -2x + 3

200

-3x + 3y = 9

y = x + 3

300

2x + 5y = 15

y = -2/5x + 3

400

2x - 3y = 12

y = 2/3x + -4

500

5x - 3y = -9

y = 5/3x + 3

Substitution

100

x = 3
y = 3x + 5

y = 14
Remember that the solution to a system of equations is a coordinate point so...

(x, y) --> (3, 14)

200

y = 12
y = 3x + 3

(3, 12)

300

y = 5x
y = 3x + 8

(4, 20)

400

y = 2x
2x + 3y = 16

(2, 4)

500

y = 2x + 4
y = 5x + 1

(1, 6)
