Answer: Option C
Step-by-step explanation:
The graph is of the quadratic equation is a parabola.
The parabola intercepts the x-axis when
.
Then, you need to substitute
into the equation:
![y=x^2+2x-8\\0=x^2+2x-8](https://tex.z-dn.net/?f=y%3Dx%5E2%2B2x-8%5C%5C0%3Dx%5E2%2B2x-8)
Factor the quadratic equation: find two number that when you add them you get 2 that when you multiply them you get -8. In this case these numbers are -2 and 4. Then:
![0=(x-2)(x+4)\\\\x_1=2\\x_2=-4](https://tex.z-dn.net/?f=0%3D%28x-2%29%28x%2B4%29%5C%5C%5C%5Cx_1%3D2%5C%5Cx_2%3D-4)
Therefore, the x-intercepts are:
(-4,0) and (2,0)
1. Pick two points on the line and determine their coordinates.
2. Determine the difference in y-coordinates of these two points (rise).
3. Determine the difference in x-coordinates for these two points (run).
4. Divide the difference in y-coordinates by the difference in x-coordinates (rise/run or slope).
