Answer:
Step-by-step explanation:
The area of a sector has the formula
Hopefully, this looks somewhat familiar to you. Theta is the central angle given as 75, r is the radius given as 4. Filling in:
and simplifying that a bit to look less threatening, but not by much:
and
Not sure how you're supposed to express your answer so I gave both the fraction and its decimal equivalency.
Answer: y=-2x + 3
Step-by-step explanation:
(0,3) and (2,-1)
3-(-1)= 4
0-2= -2
4/-2= -2 so the slope is -2 and we already know the y intercept is 3 because that is when x is 0.
so the equation will y= -2x + 3
