<PRE><B>Question 1130988</B>
ask your question this way, is point (1, 16/7) on the line 9x -7y = -7?
:
rewrite the given equation in point slope form
:
7y = 9x +7
:
y = 9x/7 +1
:
substitute 1 for x and 16/7 for y
:
16/7 = 9(1)/7 +1
:
Note that 7/7 = 1
:
16/7 = 9/7 +7/7
:
16/7 = 16/7
:
therefore the point (1, 16/7) is on the line 9x -7y = -7
