#color(crimson)("One other point on the second line is " (3, 5)#

Explanation:

#"Slope of line 1 " = m = (y_2 - y_1) / (x_2 - x_1) = (4-7) / (6-4) = -3/2#

https://math.tutorvista.com/geometry/distance-between-lines.html

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

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

#(y - 5) = -3/2 * (x - 3)#

#2y - 10 = -3x + 9#

#3x + 2y = 19#

Let y = 5. Then x = 3#
