A, it's always true
remember commutative property
a+b=b+a
a and b can be negativ numbers

so equatinos
-5.2+7.71=2.51
7.71-5.2=2.51

-8.65+3.94=-4.62
3.94-8.65=-4.62

B.
-5.2-7.71=-12.91
7.71-(-5.2)=12.91

-8.65-3.94=-12.59
3.94-(-8.65)=12.59

always false

C. when you change the order, you are subtracting a different number from a different number than before

Answer:

Step-by-step explanation:

$\frac{y}{2} =x^{2} -7$

$\frac{a}{2} =2^{2} -7$

$\frac{a}{2} =-3$

$a=-6$

$\frac{b}{2} =1^{2} -7$

$\frac{b}{2} =-6$

$b=-12$

From the calculations above, we learn that line l and the curve intersect at (2, -6) and (1, -12). Next, we will set up a system of linear equations to solve for the slope and the y-intercept of line l.

$-6=2m+b$
