A line passes through (4 ,7 ) and (6 ,4 ). A second line passes through (3 ,5 ). What is one other point that the second line may pass through if it is parallel to the first line?

Explanation:

"Slope of line 1 " = m = (y_2 - y_1) / (x_2 - x_1) = (4-7) / (6-4) = -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 - 5) = -3/2 * (x - 3)

2y - 10 = -3x + 9

3x + 2y = 19

Let y = 5. Then x = 3#
