Answer:
y = -⅔x + ²²/₃
Step-by-step explanation:
1. Calculate the slope of EF
Assume E is at (-2, 5) and F is at (1, 3).
m₁ = (y₂ - y₁)/(x₂ - x₁) = (3 - 5)/(1 -(-2)) = -⅔
2. Calculate the slope of the parallel line
m₂ = m₁ = -⅔
3. Calculate its y-intercept
y = mx + b
6 =-⅔(2) + b
Simplify
6 = -⁴/₃ + b
Add ⁴/₃ to each side
b = 6 + ⁴/₃ = ¹⁸/₃ + ⁴/₃ = ²²/₃
The y-intercept is at (0,²²/₃).
4. Write the equation for the line
y = -⅔x + ²²/₃
The diagram shows EF in red. The parallel line in black passes through (2, 6) with a y-intercept at (0,²²/₃).
Answer:
Step-by-step explanation:
I figure these exercises out by numeric association. I see a 3, so I know right away that there <em>might</em> be a 9 somewhere. So, you start by plugging 3 in for THEN plug
in for
sinse there are <em>twise</em><em> </em>the quantity of
than there are of
Now, doing so will give you
This tells you to try another pattern, so go with plugging
in for
and
in for
. Doing so gives you what you are looking --
Therefore, the association wourked perfectly. ☑
