Aphone call costs $.75 for the first 2 minutes and $.25 for each additional minute. if the total charge for the call was $10.25, how many minutes total was the phone call

42 minutes

(10.25-7.5)/0.25=42

39 minutes

0.25x+0.75

0.25(37)+0.75

$10

37mins + 2mins

39mins

the correct option is b

step-by-step explanation:

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
