Write (-2 − 2i) + (10 − 4i) as a complex number in standard form.

1)-4 + 6i
2)8 − 6i
3)6
4)12 − 6i

1 is c

2 is a

3 is a

step-by-step explanation:

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
