Equation: 
when n = 4
Step-by-step explanation:
Given
Direct Variation: P ∝ n
When n = 15, P = 150
Required
Determine the equation
Her earnings if she sold 4 necklaces
P ∝ n
Convert variation to equation

When P = 150, n = 15 (Substitute these values in the given equation)

Divide both sides by 15


Substitute k = 10 in 

------- Equation that relates P and n
When she sold 4 necklaces, n = 4
Substitute n = 4 in the formula above

Answer:

Step-by-step explanation:
This is the slope-intercept form
where
stands for the slope and
stands for the y-intercept. The slope in the picture is 9/1 or just 9 simply. The y-intercept, or where the line crosses the y-axis is at 0 so you don't have to write if there's a 0.
Hope this helps
