On a particular map in a road atlas, a distance of 70 miles corresponds to 4 cm. how many miles correspond to 11cm?

192.5 miles.

Step-by-step explanation:

We are told that on a particular map in a road atlas, a distance of 70 miles corresponds to 4 cm.

First of all let us find unit rate of the map scale. Since we know that unit rate is represented as a quantity of 1, such as 2 feet per second or 15 miles per hour.

So, 1 cm on map equals to a road distance of 17.5 miles. To find the number of miles that will correspond to 11 cm we will multiply 17.5 by 11.

Therefore, 11 cm on map corresponds to a road distance of 192.5 miles.

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
