To encourage bob to work his math problems correctly, his dad said he'd pay him 10 cents for each correct answer and charge him 5 cents for each incorrect answer. if he received a dime after doing 25 problems, how many problems did bob get right?

arithmetic sequence: a sequnce in which the diffrence between any two consecutive terms is the same

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
