Answer:
y = -4/5x + 4
General Formulas and Concepts:
<u>Pre-Algebra</u>
<u>Algebra I</u>
Standard Form: Ax + By = C
Slope-Intercept Form: y = mx + b
Step-by-step explanation:
<u>Step 1: Define</u>
Standard Form: 4x + 5y = 20
<u>Step 2: Rewrite</u>
- Subtract 4x on both sides: 5y = 20 - 4x
- Divide 5 on both sides: y = 4 - 4/5x
- Rearrange: y = -4/5x + 4
Answer:
Only B
Step-by-step explanation:
Did this in Khan Academy.
=> Also, there are 2 '-' symbols in the question.
In Option A, there is only 1 "-' symbol.
In Option B, there are 2 '-' symbols.
Option C says none of the above.
Since, Option B has 2 '-' symbols, it is the correct.
Answer:

Explanation: For this, it is often best to find the horizontal asymptote, and then take limits as x approaches the vertical asymptote and the end behaviours.
Well, we know there will be a horizontal asymptote at y = 0, because as x approaches infinite and negative infinite, the graph will shrink down closer and closer to 0, but never touch it. We call this a horizontal asymptote.
So we know that there is a restriction on the y-axis.
Now, since we know the end behaviours, let's find the asymptotic behaviours.
As x approaches the asymptote of 7⁻, then y would be diverging out to negative infinite.
As x approaches the asymptote at 7⁺, then y would be diverging out to negative infinite.
So, our range would be:
