Question

Rita traveled 1 unit left and 3 units up. She ended at the grocery store. The ordered pair describes where she started. Need coordinate grid plz ME IN RUSH PLZ ANSWER

Answer 1

(3,2)

Explanation:

Missing Information:

The coordinate of the grocery store is: (2,5).

Required:

Determine the starting point

Assume the starting coordinate is (x, y)

When a point (x, y) is translated b units left, the image of the translation is: x -> x - b

In this case:

b = 1 (i.e. 1 unit left)

So, we have:

`(x-1,y)`

When a point (x, y) is translated h units up, the image of the translation is: y -> y + h

In this case:

h = 3 (i.e. 3 units up)

So, we have:

`(x-5,y+3)`

So, the expression that describes the grocery store is:

`(x-1,y+3) = (2,5)`

By comparison:

`x-1 = 2`

`y+3=5`

Solve for x

`x = 2 + 1`

`x = 3`

Solve for y

`y = 5 - 3`

`y = 2`

Hence, the starting point is: (3,2)
