Answer:
P = 0.75
Step-by-step explanation:
Given that P varies directly as I then the equation relating thenm is
P = kI ← k is the constant of variation
To find k use the condition P = 0.5 when I = 4, thus
k = =
= 0.125
P = 0.125I ← equation of variation
When I = 6, then
P = 0.125 × 6 = 0.75
First you have to get the equation into slope/intercept format: y = mx + b
So the slope m = 2, and the y-intercept b = -1.
b tells you where the line intersects the y axis. The slope is rise (vertical distance) over run (horizontal distance). I have attached my best attempt at drawing this without graph paper. The dotted line represents the inequality, and the solution set includes the values above the line which is why it is shaded. Hope this helps!
