1) + $12, since it is a profit
2) -1440 ft, since it is below the sea level
3) - 22°F, since it is below
4) + 31 yards, since it is a gain.
The slope is the factor in front of x, so slope is 9.
The y intercept is 7 (that's the point of cross the y axis, where x=0)
There are multiple definitions of "standard form" for lines, so here are the two i can think of:
9x - y = -7 (the implicit function form)
or
y-7 = 9*(x-0) (the point-slope form)
Lmk if you have questions.

Step-by-step explanation:
Answer:
7 seconds
Step-by-step explanation:
We assume h(t) represents the height above ground, so that h(t) = 0 will be the point where the ball hits the ground.
The factored form of the equation tells us ...
h(7) = -16(7 -7)(7 +2) = 0
So, the baseball will land on the ground when t=7, seven seconds after first being thrown into the air.
_____
The other value of t that makes h(t) = 0 is -2. Since we only count time after the ball is thrown, t=-2 is an extraneous solution.
