Answer 1

The taxi charges 30 cents per mile plus a $3.00 flat fee . The total cost is $23.00

 

y = .30x  +  3.00

x is the number of miles

y is the total cost of the trip

.30 is the slope

3.00 is the y intercept

 

Solve:  23 = .30x + 3.00

 

20 = .30x

 

x = 66.67 miles

 

I can't graph this function for you... sorry!
