Answer:
y=x+1
Step-by-step explanation:
First, let's do the easiest part, finding the y-intercept, which shows up at the end of your slope intercept equation, y=mx+b, where slope is rise over run!
- Simply look for where the coordinate is on the y-intercept, which is at y = 1!
Then, we need to find our rise over run, which is basically counting from point a to point b. To get to the lower coordinate from the top, we go down two (-2), and over 4. Which means we "rose" -2, and "ran" 4! It's -2 because we went DOWN, and positive 4 because we went FORWARD. This gave us 2 over 4, which is the same as 1 over 2!

Answer:
The translation for the above map points is 8 units up and 5 units left.
Step-by-step explanation:
The translation for the above map points is 8 units up and 5 units left.
Step 1: 8 units up
(Add 8 to y co-ordinate)
Step 2: 5 units left
(subtract 5 from x-co-ordinate)
