This is the first question, and how I answered it:

Two transport companies advertise their rates for the cost of a trip:

Blue Taxis: Flagfall = $2.50 and Cost per km = $1.50 per km

Red Taxis: Flagfall = $1.25 and Cost per km= $2.25 per km

Using an algebraic method, develop a linear function for the cost (y) of a trip of distance x km for each company. Show the strategies used to find each of your equations.

My answer:

Using y=mx+c

**Blue Taxis**

m=cost per km (y-intercept)

c=flagfall (constant)

Given m=1.5, c=2.5

]y=1.5x+2.5

**Red Taxis**

m=cost per km (y-intercept)

c=flagfall (constant)

Given m= 2.25, c= 1.25

y=2.25x+1.25

Firstly, is that right?
