Since b is the y-intercept (where the line crosses the y-axis and x=0), we know it's 10; b or c. And slope is determined by taking 2 points on the graph (that is graphed or marked by the line) and divide the difference of the y coordinates by the difference of the x coordinates to get the answer, which is 2. So overall, the answer is 10:2, or C.

10:2, or C.

Hope this helped! If it didn't, tell me what went wrong so I can fix it.

Sveta_85 [38]

Answer:

10 -16 i

Step-by-step explanation:

given,

(3+ 4 i) + (7 − 20 i)

for the given complex number

if the number is added of subtracted the real part will add or subtract to the real part and imaginary will add or subtract to the imaginary part.

               = (3 + 7) + (4+(-20)) i                      

                = 10 + (-16) i                      

                = 10 -16 i
