12 years, use the slope of the line of best fit to find the best estimate for the age of the child.
ex: (3,10), (6,20), (9,30), which means the y value of 40 must be 12.
Answer:
the answer is 1/-4
Step-by-step explanation:
Answer:
(5,5)
Step-by-step explanation:
Answer:
x = 1, y = -1
Step-by-step explanation:
If we have the two equations:
and , we can look at which variable will be easiest to eliminate.
looks like it might be easy to get rid of, we just have to multiply by 2 and y is gone (as -6y + 6y = 0).
So let's multiply the equation by 2.
Now we can add these equations
------------------------
Dividing both sides by 5, we get .
Now we can substitute x into an equation to find y.
Hope this helped!
Answer: y = -3/4x - 15/16
Step-by-step explanation: Write in slope-intercept form, y=mx+b.
