<span>Linear relations are not functions when they appear graphically as:
Vertical lines
One x not one y</span>
Answer:
B. y = 1/3x
Step-by-step explanation:
The slope of the given line is -3, so the slope of the perpendicular line will be the negative reciprocal of that: -1/(-3) = 1/3. This eliminates choices A and C.
We can find the y-intercept (b) if we use the given point values in the equation ...
y = 1/3x +b
we get ...
-2 = (1/3)(-6) +b
-2 = -2 +b . . . simplify
0 = b . . . . . . . add 2
So, the equation of the perpendicular line through the given point is ...
y = 1/3x . . . . matches choice B
_____
<em>Alternate solution method</em>
You can try the given point in the given equations. You will find that only the equation of choice B will work.
Answer:
5/8
Step-by-step explanation:
Answer:
<em>The answer is (B).</em>
Step-by-step explanation:
A). y = f(x) = 6(x - 2) + 3 ⇔ y = 6x - 12 + 3 ⇔ 6x = y + 9 ⇔ x = 
g(x) = 
is inverse function of f(x) and ≠ 
- 3
<em>B).</em> y = f(x) = 
- 3 ⇔ 4y = 5x - 12 ⇔ x = 
g(x) = 
is inverse of f(x)
Answer:
When two or more separate ratios have the same value.
