Step-by-step explanation:
it is a linear function, if the change in y is constant in relation to the changes of x.
in other words, if the slope y change/x change is the same for every point.
when we look at the table, we see x changes constantly by +2.
and y changes constantly by -6.
so, the change rate/slope is constantly -6/2 = -3.
and therefore it is a linear function.
the equation looks like (the slope is always the factor of x)
y = -3x + b
b we get by using one of the x,y pairs like 1,4
4 = -3×1 + b = -3 + b
b = 7
so, the full equation is
y = -3x + 7

Answer:
B. 7 - 9i
Step-by-step explanation:
1) Remove Parentheses.
2 - 8i + 5 - i
2) Add 2 and 5.
7 - 8i - i
3) Subtract i from -8i.
7 - 9i
