Answer:
-2x+6.
Step-by-step explanation:
1) if A(1;4), B(2;2), then the required equation is:
2)
3) if to re-write this equation as slop-interception form, then:
y= -2x+6.
Answer:
see below
Step-by-step explanation:
y = a cos ( bx)
The amplitude is |a|
y = -2cos (3x) so the amplitude is |-2| = 2
The period is 2pi/b
period is 2pi/3
