Can some please help 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 ​

Answer:From textA)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.From photoa) I have never used point-slope form, but the equation in slope-intercept form is y = -3x + 30Points 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/-3m = -3 Sub a random point, (3,21) and m=-3 into slope-intercept formy = mx + b21 = -3 (3) + b21 = -9 + bIsolate bb = 30b) Initially, it took Scott 30 minutes to deliver his packages, the y-intercept. Everyday, the times decreased by 3 minutes, the slope.
