Answer:
m = -6/7
b = -2
Step-by-step explanation:
m = (y2 - y1)/(x2 - x1) = (-2 - 4)/(0 - (-7)) = -6/7
y = mx + b
m = -6/7
y = -6/7 x + b
Use point (-7, 4).
4 = (-6/7)(-7) + b
4 = 6 + b
b = -2
y = -6/7 x - 2
m = -6/7
b = -2
Step-by-step explanation:
(5−4i)(2+9i)
=(5+−4i)(2+9i)
=(5)(2)+(5)(9i)+(−4i)(2)+(−4i)(9i)
=10+45i−8x−36i2
=−36i2+37i+10
21/100 is the answer. Hope this helped!
