#color(blue)("One other point on the second line is " (0, 4)#

Explanation:

#"Slope of line 1 " = m = (y_2 - y_1) / (x_2 - x_1) = (3-6) / (7-5) = -3/2#

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 - 1) = -(3/2) * (x - 2)#

#2y - 2 = -3x + 6#

#3x + 2y = 8#

Let x = 0. Then y = 4#
