The average cost of an suv at a certain dealership over the last 10 years has ranged from $18,000 to $22,500. suppose you were going to plot these points on a coordinate grid. (1) what is a good scale to use for the y-axis? explain your reasoning. (2) what is a good interval to use for the y-axis? explain your reasoning.

1) $0-22,500.

2) $500.

Step-by-step explanation:

1) A good scale to use for this question would be $0-22,500 at least. You would start with 0 because if you have $0 then you will get no car. And all the way to at least $22,500 because that is the average cost of an SUV at that dealership within 10 years and to go any lower than that would make it inaccurate.

2) 500 would be the best interval to use for this question because 22,500 ends in 500 which means when you count by 500 you will easily get to 22,500 without counting by 1's.

(d)

step-by-step explanation:

given: the line in the graph passes through points (5,30) and (6,26).

then, the equation of line is:

now, put y=a(n) and x=n,

hence, option d is correct.

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is
