Set the equation equal to y
Add x to each side
7y=14 +x
Divide each side by 7
y=2 + x
The slope is whatever number corresponds with the variable x
In this case there is no number in front of the x which indicates that the slope is 1

Answer:
228 km
Step-by-step explanation:
Traveling 3 hours at 76 km/hour, the train covers a distance of ...
distance = speed × time
distance = (76 km/h)(3 h) = 76×3 km = 228 km
This is an example of a
sine wave function. A given sine wave function has a standard form of:
y = A sin [B (x + C)] + D
Where,
A = absolute value of
amplitude
2 π / B = the period of
the sine wave
D = is the midline of y
C = phase of the sine
wave
Rewriting the given
equation into this form will yield:
f (x) = -7 sin[4 (x – π / 4)]
+ 2
Therefore from this form,
we can get the answers:
Amplitude = 7
Period = 2π / 4 = π / 2
