Answer:
y = 9x-3
Step-by-step explanation:
since the slope intercept form is in the y=mx+b form, you just have to plug in the slope for m and the y-intercept for b.

A. We must consider that Marisa is walking a straight trail
so that the time required to cover a distance is persistent or constant.
B. The slope of the line is: y = m x + b
Where in this problem, y is the distance, m is the slope or
the time it takes for each block, x is the time, and b would be the y intercept
or the initial location of Marisa.
C. The slope m can be calculated using the formula:
m = (y2 – y1) / (x2 – x1)
m = (8 – 12) / (6 – 0)
m = -0.67
The negative sign is the space between Marisa and Sanjay’s
home is declining by time. It further means that there is a cut in 0.67 blocks
per minute.
D. y = - 0.67 x + b
The starting point of Marisa is at 12 blocks away from
Sanjay’s home, therefore let b be 12.
Finding for time when distance is y = 0:
0 = -0.67 x + 12
x = 17.9 minutes
Therefore it takes approximately 17.9 minutes to go to Sanjay’s
home.
<span>The waterbed is 7 x 4 x 1 ft, which is equal to 28 cubic ft (ft3).
The weight is (62.4 lb) per (1 cubic foot). Since the total volume is 28 cubic feet, you multiply 62.4 pounds x 28 ft3.
62.4 x 28 = 1747.2 lbs
The total weight is 1747.2 lbs</span>
