Eva is at a sushi restaurant. She ordered 2 pieces of squid for a total of $3.50, 1 piece of eel for $3.25, 3 pieces of tuna for
earnstyle [38]
2 pieces of squid = $3.50 
Therefore 1 piece of squid = $1.75 (3.50÷2)

1 piece of eel = $3.25

3 pieces of tuna = $6.75
Therefore 1 piece of tuna = $2.25 (6.75÷3)

4 pieces of crab = $8.00 
Therefore 1 piece of crab = $2 (8÷4)

Put them in order of price and you get 

$1.75 , $2 , $2.25 , $3.25

The points (x, 3) and (-2, 2) have a slope of 1. What is the x-coordinate of the point<br> (x, 3)?
Naya [18.7K]

Answer:

(-1,3)

Step-by-step explanation:

The slope is given by

m = (y2-y1)/(x2-x1)

1 = (2-3)/(-2-x)

Multiply each side by (-2-x)

(-2-x) = -1

Multiply by -1

2+x = 1

Subtract 2 from each side

2+x-2 = 1-2

x = -1
