The lower quartile is quartile 1. The graph shows it as "-4". So the answer is D.
Answer:
2 or 2/1
Step-by-step explanation:
Rise over run. Up 2 and right 1.
Hopefully this helps :)
First find the equation of the line:
y - b = m (X - a)
y - 5 = 2/3 (X + 2)
3y - 15 = 2 (X + 2)
3y - 15 = 2x + 4
3y = 2x + 19
Then sub the y-value of A into the equation to find X.
y = 3
3(3) = 2x + 19
9 = 2x + 19
2x = 10
X = 5
And sub the X-value of B into the equation to find y.
X = -2
3y = 2(-2) + 19
3y = -4 + 19
3y = 15
y = 5
