Question 5
See example 1 on page 1 of notes.
A 40 degree clockwise rotation is the same as a ( )
degree rotation counterclockwise.
A 210 degree counterclockwise rotation is the same as a ( )
degree rotation clockwise.

A) 320

B) 150

Step-by-step explanation:

The whole turn from starting point, coming back to the same point would be 360 degrees. So subtraction 360 degrees from rotation would give you the direction it is needed to travel the other direction.

Hope this helps

y=3x+4

step-by-step explanation:

given the points a(0,4) and b(-4, -8)

eqn of line ab: (y-4)/(x-0)=(-8-4)/(-4-0)

(y-4)/x=-12/-4=3

y=3x+4
