Write as a fraction (no improper fractions):
1.4

1 2/5

Step-by-step explanation:

Step 1:

1.4 = 140/100

Step 2:

140/100 = 70/50

Step 3:

70/50 = 35/25

Step 4:

35/25 = 7/5

Step 5:

7/5 = 1 2/5

1 2/5

Hope This Helps :)

First, you need to know what "m" and "b" represents.

"m" represents slope, and "b" represents the y intercept.

For the equation you can combine the information to get y = mx + b

To find "m" indentify points, and see how many you have to go up/down then left/right.

To find "b" since the graphis given see where the line crosses the y axis. (0, b)

1. m = -1, b = 3

y = -1x + 3

2. m = 1, b = -3

y = 1x -3

3. m = 3/1 or 3, b = 1

y = 3x + 1

4. m = -3/1 or -3, b = -3

y = -3x -3
