car travelpart A.Issa write the equation y=55x to model the distance in miles y travrling x in hoirs in car.which graph models the equation.part b.time/hours. distance/miles2. 90 4. 1806. 270Compare the speed of the train to the speed of the car.how much less time would it be for lissa to travel 231 miles using the faster Mode of transportation.explain how you find the answer.

Answer 1

Firstly, we need to compare the given equation to the standard form

The standard form is;

`y\text{ = mx + b}`

where m is the slope that represents the unit rate

So, the graph that will be correct will be the one that has its slope as 55

From the plots, we can see that the first is correct

Looking at the point (1,55) and (2,110) slightly multiplies the values on the x-axis by approximately 55 which is the rate and thus the plot is correct

From the second graph, we can see the part (1, 100) which cannot be correct

From the third plot, we have the values on the y-axis as incorrect as they need to be larger

Secondly, we can see that the rate is 55 which represents traveling 55 miles per hour
