#color(violet)("One other point on the second line is " (7,4)#

#"Slope of line 1 " = m = (y_2 - y_1) / (x_2 - x_1) = (5-8) / (1-2) = 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 - 1) = 3 * (x - 6)#

#3x - y = 17#

Let y = 4. Then x = 7#
