The first thing you should do is verify that the ordered pairs satisfy equality. If so, then that pair ordered belongs to the line. Let us begin:
3x-4y = 9
(-1.3)
3 (-1) -4 (3) = 9
-3-12 = 9
-15 = 9 (Does not belong)
(2/3, -7 / 4)
3 (2/3) -4 (-7/4) = 9
6 + 28 = 9
34 = 9 (Does not belong)
(-5, -6)
3 (-5) -4 (-6) = 9
-15 + 24 = 9
9 = 9 (Yes, it belongs)
(1, -3 / 2)
3 (1) -4 (-3/2) = 9
3 + 6 = 9
9 = 9 (Yes, it belongs)
answer
ordered pairs are
(-5, -6)
(1, -3 / 2)
Answer:

Step-by-step explanation:
The point-slope form of an equation of a line:

We have the slope m = 3 and the point (-2, 3). Substitute:

the point-slope form
<em>use the distributive property</em>
<em>add 3 to both sides</em>

the slope-intercept form
<em>subtract 3x from both sides</em>
<em>change the signs</em>
the standard form
<em>add 9 to both sides</em>

the general form
Answer:
x=0
Step-by-step explanation:
You are asked what is the number to be use as the exponent of
, in order to get as answer "1".
Use the property of exponents that sates that : 
In your case
so the exponent "x"must be = 0 (zero)
