If she got 5/100 wrong she got 95%
95% is the same as 0.95
Simply solve for x:
-x^2 + 9 = 0 => x = 3 and x = -3;
plug x = 3 and x = -3 into the original equation you get 3 = 3 and -9 = -9, respectively;
So, the two intersecting points are (-3, -9), (3, 3).
And of course, the parabola opens down since its square term is minus.
Missing part of question
(a) (-3, 4) and (5, 4)
(b) (4, 5) and (4, -3).
Answer:
(a) (-3, 4) and (5, 4)
Zero slope
Horizontal line
(b) (4, 5) and (4, -3).
Undefined slope
Vertical line
Step-by-step explanation:
Solving (a): (-3, 4) and (5, 4)
Slope (m) is calculated as:
![m = \frac{y_2 - y_1}{x_2 - x_1}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7By_2%20-%20y_1%7D%7Bx_2%20-%20x_1%7D)
This gives
![m = \frac{4-4}{5 - -3}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7B4-4%7D%7B5%20-%20-3%7D)
![m = \frac{0}{8}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7B0%7D%7B8%7D)
![m = 0](https://tex.z-dn.net/?f=m%20%3D%200)
This line has a slope of zero.
When slope equals 0, then the line is horizontal
Solving (b): (4, 5) and (4, -3)
Slope (m) is calculated as:
![m = \frac{y_2 - y_1}{x_2 - x_1}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7By_2%20-%20y_1%7D%7Bx_2%20-%20x_1%7D)
This gives
![m = \frac{5--3}{4-4}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7B5--3%7D%7B4-4%7D)
![m = \frac{8}{0}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7B8%7D%7B0%7D)
<em>m = undefined</em>
This line has an undefined slope.
When the slope of a line is undefined, then the line is vertical
