#color(maroon)("One other point on the second line is " (6,9)#

#"Slope of line 1 " = m = (y_2 - y_1) / (x_2 - x_1) = (9-3) / (2-4) = -3#

As #2^(nd)# line is parallel to the first line, slope of second line also #-3#

#"Equation of second line in point - slope form is "

#(y - 6) = -3 * (x - 7)#

#3x + y = 27#

Let y = 9. Then x = 6#
