if the line is parallel is has the same slope so it will be a horizontal line
it must pass thru the point (7,5)
y =5
y = 5
the equation y = c is a horizontal line parallel to the x-axis and passing through all points with a y-coordinate equal to c
y = - 7 is a horizontal line
the line parallel to it and passing through (7, 5 ) is therefore
y = 5 ( 5 being the value of the y-coordinate )
