The answer has to be the lowest negative number
Any linear equation can be written as
y = mx+b
where m is the slope and b is the y intercept
m = 1/2 in this case. It represents the idea that the snow fell at a rate of 1/2 inch per hour. In other words, the snow level went up 1/2 an inch each time an hour passed by.
b = 8 is the y intercept. It's the starting amount of snow. We start off with 8 inches of snow already.
The info "snow fell for 9 hours" doesn't appear to be relevant here.
The answer to that is 0. The distance in the y direction is 12 and there are 6 parts 5 before the point and 1 after. So 12/6 = 2 or the length of each part
add 5*2 to -10 = 10 - 10 = 0 that is your answer
Step-by-step explanation:
4x - 5y = -20
-5y = -4x -20
y = 4/5x + 4
