Slope-intercept form is y=mx+b, where m is the slope and b is the y-intercept. Since we are given slope, we can plug that into m, and use the given point to find the y-intercept.

$y=\frac{3}{4}x+b$ [plug in (8,9)]

$9=\frac{3}{4}(8)+b$ [multiply]

$9=6+b$ [subtract both sides by 6]

$b=3$

Now that we have b, we can complete the equation to $y=\frac{3}{4}x+3$ .

Answer:

Step-by-step explanation:

Jack's rate = 28/2 = 14 boxes/hour

Walter's rate = 36/3 = 12 boxes/hour

Combined rate = 14 + 12

= 26 boxes/hour

26 = 65/t

26t = 65
