find linear equation

Question

A cab company charges a $5 boarding rate in addition to its meter which is $3 for every mile. What is the equation of the line that represents this cab company’s rate?

(thxs a lot for anyone solving it,the ans is y=3x+5 but how do u get the ans)

Answer 1

The answer y=3X+5 is correct. General formula for a linear equation is: y=aX+b in which X is No. of miles, y is the total charges of the cab, and a and b are constants. In this case, a=$3 charge for each mile, and b=$5 boarding charge. For instance, if the cab drives 10 miles, the cab driver will charge the passenger y=3*10+5 which means $35.

Answer 2

Hello Nimay,

The cab co. charges $3 for every mile so if it travels x miles, the cost will be 3x

To set it in the form of equation of line y=mx+b, determine each term.

m is slope or rate of change which is 3, x miles and b is y intercept which is 5 So equation is. y=3x+5
