One liter is approximately 1.06 quarts. Write a direct variation equation that relates x liters to y quarts.

y= 1.06x

Step-by-step explanation:

We can write an expression for a direct variation equation as

y=kx

K= constant of proportionality

Then, to write direct variation equation that relates x liters to y quarts, we know that k= 1.06 quarts. which is constant, if we substitute we have

y= 1.06x

b

step-by-step explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (3, - 5) ← 2 points on the line

m = = = - 3

with m = - 3 and (a, b) = (3, - 5), then

y - (- 5) = - 3(x - 3), that is

y + 5 = - 3(x - 3) → b
