Step-by-step explanation:
<u>Find zeros first:</u>
- x² + x - 6 = x² + 3x - 2x - 6 = x(x + 3) - 2(x + 3) = (x - 2)(x + 3)
- x = 2, x = -3, x = 7 (but x ≠ 7 as no division by zero)
<u>We have 4 intervals:</u>
- x ≤ - 3, three negatives, the result is negative or zero
- -3 ≤ x ≤ 2, two negatives and one positive, the result is positive or zero
- 2 ≤ x < 7, two positives and one negative, the result is negative or zero
- x > 7, three positives, the result is positive or zero
<u>The solution is:</u>
Correct choice is A

the answer is the last one

Hello!
Ok so ideally we would like to see this in y=mx+b form. But it will take some algebreic skills to ninja our way through this.
I'll show my steps so you can follow,
3+4x = 2y - 9 (original equation)
Next we just add 9 to both sides,
12 + 4x = 2y, now we can divide both sides by 2,
y=2x+6 as our final equation. This is in y=mx+b form, thus the slope of our line is 2 because the 2 is sitting in the m space of the equation. If you still dont understand linear stuff, I'd google slope-intercept form
Hope this helped!
16/4= 4 so the 16+4=20 and 20 is the answer
