First you find your slope which is rise/run, so, 1/3, and a line this way (/) is positive, so it's positive 1/3.
Then you see where it crosses the y axis: -1.
Plug that into y=mx+b giving you y=1/3x-1.
Your answer is D.
6/1 ÷ 3/4
= 6/1 × 4/3
= 24/3
= 8
Andy's equation is incorrect and the correct equation of the line is y + 2= 3/4(x - 3)
<h3>How to determine the equation of the line?</h3>
The given parameters are:
Slope, m = 3/4
Point, (x,y) = (3,-2)
The equation of the line is calculated using:
y - y1 = m(x - x1)
Substitute the known parameters
y + 2= 3/4(x - 3)
From the question;
Andy's equation is y + 2 = 3/4(x - 9/4)
The above equation is different from the actual equation y + 2= 3/4(x - 3)
Hence, Andy's equation is incorrect and the correct equation of the line is y + 2= 3/4(x - 3)

Answer:
4√15
Step-by-step explanation:
The geometric mean of x and y is √(xy).
So here we have:
√(12*20)
= √240
= √(16*15)
= √16√15
= 4√15.
C is the correct answer
good luck
