Answer:
12 (or A)
Step-by-step explanation:
A coefficient is the number before a variable.
Examples: 5r , 34y, 10x^2 (the coefficients are 5, 34, and 10)
12 has a variable after it, so 12 is a coefficient.
slope=(0-3)/(3-0)=-3/3=-1
y intercept=3
eq. of line is y=-x+3
19
false
3×-8=-24
-171+9=-162
so -24 is not equal to-162
