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:

(3,2)

Step-by-step 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:

[tex](x-1,y)[/tex]

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:

[tex](x-5,y+3)[/tex]

So, the expression that describes the grocery store is:

[tex](x-1,y+3) = (2,5)[/tex]

By comparison:

[tex]x-1 = 2[/tex]

[tex]y+3=5[/tex]

Solve for x

[tex]x = 2 + 1[/tex]

[tex]x = 3[/tex]

Solve for y

[tex]y = 5 - 3[/tex]

[tex]y = 2[/tex]

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