Can some me with this question needs to be turned in today asap. ( question 2) the average cost of a compact car at a certain dealership over the last 10 years has ranged from $14,000 to $18, 500. suppose you were going to plot these points on a coordinate grid. a) what is a good scale to use for the y-axis? explain your reasoning. b) what is a good interval to use for the y-axis? explain your reasoning. will mark brainliest

From text

A)

A good scale to use for the y-axis is 500 for each square, starting from 14,000 to skip the irrelevant numbers less than 14,000. The numbers and range are very large, so a scale of 500 makes the y-axis about 10 squares high.

B)

A good interval to use for the y-axis is 500. Both 14,000 and 18,500 are multiples of 500.

a) I have never used point-slope form, but the equation in slope-intercept form is y = -3x + 30

Points on the graph are (3, 21) and (6, 12).

The slope is found with the equation m = (y2-y1)/(x2-x1)

m = (21-12)/(3-6)

m = 9/-3

m = -3

Sub a random point, (3,21) and m=-3 into slope-intercept form

y = mx + b

21 = -3 (3) + b

21 = -9 + b

Isolate b

b = 30

b) Initially, it took Scott 30 minutes to deliver his packages, the y-intercept. Everyday, the times decreased by 3 minutes, the slope.

step-by-step explanation:

this woman was an important writer and propagandist during the american revolution. she was a member of the committee of correspondence (in fact the committee was formed in her home) and was an advisor to many of the revolutionary leaders, including george washington and john adams. who was this revolutionary woman?

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.
