The given line passes through the points (0, -3) and (2, 3).
wvat is the equation, in point slope form, of the line that is
parall to the given line and passe through the point
(1
y+ 1
(x1)
(0,3

This is a linear equation  y= mx + b, where m is the slope.
It passes through 2 points A & B having the respective coordinates
A(x₁,y₁) & B(x₂,y₂). Given A(0,-3) & B(2,-3)

1st calculate the slope: m=(y₂-y₁)/(x₂-x₁) ==> (-3-3)/(2-0)==> m =-6/2 = -3

y = -3x + b. To calculate b, plug the coordinate of either A or B, let's take A
-3= -3(0) + b ==>b= -3
Final equation: y = -3x - 3  or y+3 = -3x

Period is the time it takes for one “cycle” to complete. in the parent sine function, period is 2*pi since sin(0) = 0, sin(pi/2) = 1, sin(pi) = 0, sin(3pi/2) = -1, and sin(2pi) = 0. at that point, the sequence repeats itself. i’m not sure if your graph is similar to the sine function since you didn’t provide a picture, but you can find the period by looking at a graph.
