Answer:
slope = -3
Step-by-step explanation:
1) Rearrange eqn into slope intercept form
slope intercept form: y = mx + b
where...
m = the slope
b = the y-intercept (where the line crosses the y axis)
3x + y = 12
y = -3x+12
2) Know parallel rule. A line that runs parallel has the same slope but a different y-intercept
So the slope is: -3
Answer:
7 seconds
Step-by-step explanation:
Hello There!
I had created a graph to make it easier to understand
So when y = 0 is when the ball is at the ground
when y = 0 x = 7 so it took about 7 seconds for the ball to hit the ground

How to calculate the coordinate of point by reflection</h3>
A point if reflected across the line
by means of the following formula:
(1)
Where:
- Original point
- x-Coordinate of point P
- Resulting point
If we know that
and
, then the coordinates of the vertex is:
![P'(x,y) = (-2, 4) + 2\cdot [(-2,-2)-(-2,4)]](https://tex.z-dn.net/?f=P%27%28x%2Cy%29%20%3D%20%28-2%2C%204%29%20%2B%202%5Ccdot%20%5B%28-2%2C-2%29-%28-2%2C4%29%5D)
