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

#"Slope of line 1 " = m = (y_2 - y_1) / (x_2 - x_1) = (5-6) / (4-3) = -1#

As #2^(nd)# line is parallel to the first line, slope of second line also #-1#

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

#(y - 3) = -1 * (x - 7)#

#x + y = 10#

Let y = 5. Then x = 5#

graph{-x + 10 [-10, 10, -5, 5]}
