Answer:
Slope (m) = infinity
Step-by-step explanation:
Given points:
⇒ (9, 2) and (9, 27)
In order to find the <em>slope</em> of these points, we must use the <em>slope</em> formula.
So the formula is ⇒ y₂ - y₁ / x₂ - x₁
<em>Plug</em> in the<em> given </em>points:
⇒ 27 - 2 / 9 - 9
Solve both the top and bottom (<em>numerator and denominator</em>):
⇒ 25 / 0
Divide:
⇒<em> Undefined. </em>
(<em>Anything</em><em> </em>divided by <em>zero</em> is undefined).
Answer:
a number divided by 4
Step-by-step explanation:
a number = n (it's a variable used in equations.)
so n over 4, or n divided by 4
If 
, then 
and 
because 
lies in the fourth quadrant.
By DeMoivre's theorem,
so the answer is B.
y = mx + b
m: slope
b: y-intercept
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
3x + 9y = 18
-3x -3x
9y = -3x + 18
/9 /9
y = -3/9x + 2 OR y = -1/3 + 2
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
m = -3/9 OR -1/3
b = 2
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Answer:
Step-by-step explanation:
Lets say Rhonda drove x miles, then Jamie drove 2x miles
x+2x=90
3x=90 divide each side by 3
x=30
so Rhonda drove 30 miles and Jamie drove 30*2=60 miles
