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)

What is the equation of the line slope of 3 and passes through the point (-2, 3)?
elixir [45]

Answer:

\large\boxed{y-3=3(x+2)}\qquad\text{point-slope form}\\\boxed{y=3x+9}\qquad\text{slope-intercept form}\\\boxed{3x-y=-9}\qquad\text{standard form}\\\boxed{3x-y+9=0}\qquad\text{general form}

Step-by-step explanation:

The point-slope form of an equation of a line:

y-y_1=m(x-x_1)

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

y-3=3(x-(-2))\\\\y-3=3(x+2)

the point-slope form

y-3=3(x+2)        <em>use the distributive property</em>

y-3=3x+6           <em>add 3 to both sides</em>

y=3x+9

the slope-intercept form

y=3x+9           <em>subtract 3x from both sides</em>

-3x+y=9         <em>change the signs</em>

3x-y=-9

the standard form

3x-y=-9              <em>add 9 to both sides</em>

3x-y+9=0

the general form

Step-by-step explanation:

You are asked what is the number to be use as the exponent of 7^{2}, in order to get as answer "1".

Use the property of exponents that sates that : a^0=1

In your case a=7^2=49 so the exponent "x"must be = 0 (zero)
