Answer:
y = 9/5 x -4
Step-by-step explanation:
first find slope or m
slope is change in y over the change in x
-4-5/0-5 =-9/-5 = 9/5
the (0, -4) is the y intercept or b
Answer:
r = -1
Step-by-step explanation:
(y2-y1)/(x2-x1)=m
(r,7)=(x1,y1) and (3,4)=(x2-y2) and m=-3/5
so plug in...
(4-7)/(4-r)=-3/5
then solve for r which will get that r = -1
numerator: 4-7=-3
denominator: 4-r=5 -> 4-5=0+r -> -1=r
Answer:
5π/3 radians
Step-by-step explanation:
The central angle for arc CBD has the same measure as the arc:
300° = 5π/3 radians
_____
180° is π radians, so (5/3)(180°) = 300° = (5/3)π radians.
