Pls help and tell me what points to do and I’ll give u brainliest

See explanation and picture below.

Step-by-step explanation:

When the storm began, there was an inch of snow on the ground.

The time on the graph is the number of hours since the storm began.

At the time the storm began, no time had passed since the storm began, so at the time the storm began, time was zero. At zero time, the snow was 1 inch. That gives you the point (0, 1).

For the next 6 hours, snow fell at a constant rate of 1 inch per hour.

At time 1 hour, there were 2 inches of snow. Point: (1, 2).

At time 2 hours, there were 3 inches of snow. Point (2, 3).

At time 3 hours, there were 4 inches of snow. Point: (3, 4).

At time 4 hours, there were 5 inches of snow. Point (4, 5).

At time 5 hours, there were 6 inches of snow. Point: (5, 6).

At time 6 hours, there were 7 inches of snow. Point (6, 7).

The storm then stopped for 3 hours. That means for the next 3 hours after time 6 hours, the snow stayed at 7 inches.

Points: (7, 7), (8, 7), (9, 7).

Then the storm started up again dropping 3 inches of snow per hour for the next 4 hours.

That gives us the next 4 points, in which the hour goes up one by one, and the snow goes up three by three.

Points: (10, 10), (11, 13), (12, 16), (13, 19).

Now you need to plot all the points in bold above and connect them with line segments.

See the picture below.

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.
