Question

the graph relates the number of gallons of white paint to the number of gallons of red paint jess used to make the perfect pink. write an equation that describes the relationship.
the equation $square$ describes the relationship.
(simplify your answer.)

Explanation:

Step1: Identify slope from graph

The line passes through (0,0) and (4,1). Calculate slope:
$m = \frac{1-0}{4-0} = \frac{1}{4}$

Step2: Write linear equation

Since y-intercept is 0, use $y = mx$:
$y = \frac{1}{4}x$
(Here, $y$ = red paint, $x$ = white paint)

Answer:

$y = \frac{1}{4}x$
