Answer:
The amplitude is 4 and the period is 2
Step-by-step explanation:
In the equation y = A sin (B x)
- A is the amplitude, where the amplitude is the height from highest to lowest points and divide the answer by 2
- The period is
, where the period is the distance from one peak to the next peak
∵ The equation is y = 4 sin(πФ)
- Compare it with form above
∴ A = 4 and B = π
∵ A is the amplitude
∴ The amplitude is 4
∵ Period =
∴ Period = 
∴ Period = 2
∴ The period is 2
Solution
We must must transform the standard form equation 3x+6y=5 into a slope-intercept form equation (y=mx+b) to find its slope.
3x+6y=5 (Subtract 3x on both sides.)
6y=−3x+5 (Divide both sides by 6.)

is equal to 2, therefore 2 is the slope of our line.
Since the equation of line passing through the point (1,3), therefore substitute the given point in the equation y=2x+b:
3=(2×1)+b
3=2+b
b=3−2=1
Substitute this value for b in the equation y=2x+b:
y=2x+1
Hence, the equation of the line is y=2x+1.
I don't know if my answer is correct but I hope it helps
Y = 3.8x + 17.4
y = (3.8 x 3) + 17.4
y= 11.4 + 17.4
y = 28.8
