Answer:
Slope: 2/3
Step-by-step explanation:
Point 1: (3, -1)
Point 2: (0, -3)
y^2-y^1/x^2-x^1
-3+1/0-3 = -2/-3 =2/3
Just divide 216 by 8. 216÷8=27.
8 times

= 216
Answer:
4a + 2b/3
Step-by-step explanation:
focus on 8b/12 first:
factor 8b/12 by 4 ---> 8b/12 = 4(2)b/4(3) ----> cancel 4 in the denominator and the nominator ---> 8b/12 = 4(2)b/4(3) = 2b/3
then, go back to 4a:
4a is in its simplest form, it can't be factor
therefore, plus 4a and 2b/3 = 4a + 2b/3
The line of symmetry.
It divides the parabola into to halves that are exactly the same.
