Slope intercept form is
y = mx + b
where m is the slope and b is the y intercept.
Here we have
y = 9x - 2
so a slope of 9 and y intercept of -2
Answer: third choice
By using the PEMDAS order of operations, we get 3(6+7) = 39.
The equation be 3(6+7) then the correct answer is 34.
<h3>What is PEMDAS order of operations?</h3>
The order of operations exists as a law that describes the proper sequence of stages for estimating a math expression. We can recognize the order utilizing PEMDAS: Parentheses, Exponents, Multiplication, Division (from left to right), Addition, and Subtraction (from left to right).
Given: 3(6+7)
By using the PEMDAS order of operations, we get
(6+7) = 13
Then we get
3(6+7) = 3 
13
= 39.
Therefore, the value of 3(6+7) = 39.

The equation would be as follows where g = gravity constant and v(o) = initial velocity, t = time in seconds and h(o) = initial height:
<span>h(t) = -1/2gt^2 + vt(o) +h(o) </span>
<span>h(t) = -16t^2 + 28t + 0...assuming ball was somehow tossed while lying on your back. </span>
<span>for example: </span>
<span>h(1) = -16ft(1^2) + 28(1)ft + 0 ft = 12 ft. </span>
<span>OK...revisited problem after reading your additional details: </span>
<span>h = -16t^2 + 28t + 7 </span>
<span>h' = -32t + 28 </span>
<span>-32t + 28 = 0 </span>
<span>-32t = -28 </span>
<span>t = .875 seconds </span>
<span>h(.875) = -16(.875^2) + 28(.875) + 7 </span>
<span>h(.875) = 19.25 ft </span>
<span>So rounding time to nearest hundredth gives max at (.88s, 19.25ft)</span>
