Answer:
The answer is option C
Step-by-step explanation:
Equation of a line is y = mx + c
where
m is the slope
c is the y intercept
To find the equation of the parallel line we must first find the slope of the original line
The original line is
y = 7x + 15
Comparing with the general equation above
Slope = 7
Since the lines are parallel their slope are also the same
Slope of other parallel line = 7
So the equation of the line using point
P(9,6) and slope 7 is
y - 6 = 7( x - 9)
