2x – 4y = 8

What is the slope?

1/2

3x + 4 y = -20

Find the y-intercept

-5

4x – 5y = -30

Put the equation in slope-intercept

form

Y = 4/5x + 6

Write the equation of a line with slope 3

through (2, -5)

y = 3x -11

Write the equation of a line through

(2, 4) & (4, 8)

y = 2x

y = x + 3

y – 2x = 5

(-2, 1)

y = 3x + 8

y – 3x = -7

No solution

x – y = 3

x + 5y = 39

(9, 6)

-2x + 10y = -8

x – 5y = 4

infinite solutions

2x + y = 7

x – 3y = 0
