Darren spends 39 minutes studying for his science test. He the does 6 chores. Each chore takes him 3 minutes. How many minutes does Darren spend studying and doing his chores?

57 minutes

Step-by-step explanation:

6*3=18 minutes then if you add 18+39 you get 57

the function makes a strait line horizontally with no x intercept but a y intercept at 9.

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
