It seems some part of the text is missing, however, since we are talking about 'crests' I guess we are talking about waves.
In a wave, the distance between two consecutive crests corresponds to the wavelength of the wave. Therefore, the distance measured with the ruler is the wavelength of the wave.
Answer:
(−13/2,−289/4)
Step-by-step explanation:
Answer:
-5/2
Step-by-step explanation:
Slope m = (y2-y1)/(x2-x1)
m = (-2 - 8)/(6 - 2) = -10/4 = -5/2
so y = mx + b
y = -5/2x + b
Using (2,8)
8 = -5/2(2) + b
8 = -5 + b
b = 13
then y = -5/2x + 13
