Answer:
The answer on the top is the best line for a line of best fit because...
Step-by-step explanation:
there is a noticeable correlation in the first graph- a positive one. The line of best fit should have about the same amount of line plots on the top than on the bottom. Also, there can be a few line plots that is touching the line of best fit as well. Those line plots will be about the middle of the data and provide a good guideline to make your line of best fit the most accurate. The second graph is pretty scattered and doesn't have a clear correlation therefore having no correlation. Hope this helps!!
Answer:
6/5
Step-by-step explanation:
Slope = Rise/Run = y2-y1/x2-x1
To find the inverse, swap the x's and y's and solve for y. <em>Remember that a(x) represents y</em>
y = - 2 <em>given</em>
x = - 2 <em>x's and y's swapped</em>
x + 2 = <em>added 2 to both sides</em>
y(x + 2) = 1 <em>multiplied y on both sides</em>
y = divided (x + 2) on both sides
Answer: =
