A hospital volunteer plans to work with patients for 1 hour every Monday, 1 hour every Wednesday, and 3 hours on Fridays. The
graph shows the number of hours he plans to work for a given
number of weeks. Which equation describes the relationship?
How many hours will he volunteer in 16 weeks?

32/80  

91/140

the last one 54 doesn't go into 45. 54/100 ?

step-by-step explanation:

thats not a system of equations, that is a solution

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
