Welcome to Corner Kitchen, where every recipe is a table and every table becomes a picture. Plot each batch as a point and watch equal ratios line up straight through the origin.
Bienvenido a Corner Kitchen, donde cada receta es una tabla y cada tabla se convierte en una imagen. Marca cada tanda como un punto y mira cómo las razones iguales se alinean en línea recta por el origen.

- 1:4
- 2:8
- 3:4
- 4:1

- Student A
- Same steepness
- Cannot tell
- Student B
- What is the best next move?

- Why do the points form a straight line through (0, 0)?
- Because the quantities are proportional — the same ratio holds for every pair
- Because the owner sold the same number of tacos every day
- Because all graphs of data are straight
- Because salsa is measured in ounces
- Which point would NOT be on this line?
- (4, 8)
- (5, 12)
- (6, 12)
- (10, 20)
- What do the points of equal ratios look like on a coordinate plane?
- They fall on a straight line through the origin.
- They make a curve that bends upward as x grows.
- They make a straight line that starts at y = 1.
- They make a flat line, since the ratio stays the same.
