Answer:
3/17 or 17.64%
Step-by-step explanation:
Answer:
-5
Step-by-step explanation:
The equation is in slope intercept form. 
8 replaces b, so it is the y-intercept.
-5 replaces m, so it is the slope.
D - -x^2 + 3x + 7
To find this, first write out the equation:
(3x + 1) - (x^2 - 6)
Distribute the negative into x^2 and -6 so you're equation now looks like this:
3 x + 1 - x^2 + 6
Combine like terms and arrange the equation into ax^2 + bx + c to get the final answer of:
-x^2 + 3x + 7
Hope this helps!
