The scatter plot graph shows the average annual income for a certain profession based on the number of years of experience which of the following is most likely to be the equation of the trend line for this set of data? a. i=5350e +37100 b. i=5350e-37100 c. i=5350e d. e=5350e+37100

a. I=5350E +37100

Step-by-step explanation:

The trend line does not start at the origin so we can immediately rule out option C

The equation should be in slope intercept form so we can rule out option D, since E is the x axis and we are looking for y = mx + b not x = mx + b.

Option B is ruled out because if we plug in the value of E = 2 then we get:

I = 5350(2) - 37100

I = 10700 - 37100

I = -16400

Which is wrong since we are not in the negative so your answer is A

4a. is 3 miles every hour

4b. is 1/3 of an hour per mile

step-by-step explanation:

the correct answer is x/3+10≥32

hope this !
