The answer is C. The slope formula, y2-y1 over x2-x1, which can be remembered as rise over run, can be used to solve. The y2 is 7 as it is the second y and then 1, the first y, is subtracted from it. 7-1=6. After this, you find the second x which is 3, and subtract -6 from it, meaning that you add it as you are subtracting a negative and they cancel out. You now have 3-(-6), or 3+6 on the bottom and 7-1 on the top. 7-1=6 and 3+6=9. The answer is the 6/9 and can be simplified down to 2/3 because of their shared greatest common factor, 3. Hope this helps.
Honestly, I don't know if I'm correct but I think it's

Answer:
Step-by-step explanation:
To isolate the term of x from one side of the equation, you must multiply by a polynomial.
<u>You have to solve with parentheses first.</u>
<u>Solve.</u>
x(-5x)=-5x²
3*3x²=9x²
3(-5x)=-15x
3(-10)=-30
<u>Then, rewrite the problem down.</u>
<u>Combine like terms.</u>
<u>Add/subtract the numbers from left to right.</u>
-5x²+9x²=4x²
<u>Solve.</u>
<u>Then rewrite the problem.</u>
- <u>Therefore, the correct answer is 3x³+4x²-25x-30.</u>
I hope this helps! Let me know if you have any questions.
