A pilot takes a taxi from the airport to the hotel. The taxi driver charges a $2.50 initial charge plus $2.65 per mile. Which equation can be used to find y, the total cost of the trip, if x represents the number of miles of the trip? a y = 2.65(x + 2.50)
b y = 2.65x-2.50
c y = 2.50x+2.65
d y = 2.65x+2.50

d y=2.65x+2.50

Step-by-step explanation:

The correct answer would be d because y is the total cost with a start value of 2.50 and a slope of 2.65x. Then you would just replace the equation y=mx+b with these values

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4

1.30
