Answer: y = 1/2 x 7
Step-by-step explanation:
Get the apparent line that generally passes through the mean values of the values represented in the scatter plot. Find the Slope.
The easiest way is to the difference between the highest and lowest y-values (or the average of two of the highest and lowest) So around about 17.5 - 8.5 = 9 Divide by the difference in x-values 18- 1 = 17 9/17 ≈ .53 Round to .5 ≈1/2
Of the choices given, only the last one has the correct slope. If you were to graph this line, passing through the apparent mean of the values (about half the points above and half below the line) it would intersect the y-axis at about y=7
