Take any two points to find the slope of a line. The slope will be equal to:
(y2-y1)/(x2-x1) and any two points will do...
I'll use (-2,4) and (0,0) :P so the slope is:
(0-4)/(0--2)=-4/2=-2, now we know the slope is -2 so:
y=-2x+b (now we know b=0, but I'll use another point anyway to solve for b)
Let's use (-2,4) again...
4=-2(-2)+b
4=4+b
b=0
So the line is:
y=-2x
hope this helped!
First u get a fraction strip or make one then go to the denominator u count by how many the nomerator is then go to the other fraction and the same thing which ever is more is the greatest hope this helped.
Answer:
0.9168
4th data point.
Step-by-step explanation:
Using the estimated data point culled from the attached graph, the correlation Coefficient for the plotted regression data should be approximately 0.9168 which depicts that a strong positive correlation exists between the Electricity bill ($) and the time spent at home because the Coefficient obtained is very close to 1. And the measure if the strength of a relationship using the correlation Coefficient is how close the R value is to either ±1.
The electricity bill that should be ignored to improve the correlation Coefficient is the 4tg data point on the graph as it is farthest away from the regression line when compared to other points.
Answer:
C. 2x
Step-by-step explanation:
Let
B's age = x years
A's age = 2 times older than B
= 2 * x
= 2x years
A's age = 2x years
For instance, if B's age is 17 years
Then,
A's age = 2x
= 2(17)
= 34 years old
