Answer:
The standard form is 
Step-by-step explanation:
The standard form of a linear equation can be written as
The given equation is
This equation is in the slope-intercept form.
To rewrite this in standard form, we must multiply through by the least common multiple which is 4.
We now add 
to both sides of the equation to obtain,
This simplifies to
Hence the standard form is
The correct answer is A
Answer: They are not parallel, they are coincident
Step-by-step explanation:
If two lines have the same slope but a different y-intercept, the lines are parallel. If two lines have the same slope and the same y-intercept, the lines are coincident.
We can rewrite 5x−y=−5 adding -5x to both sides and multiplying by -1:
5x - y =-5
5x - y -5x = -5 - 5x (adding -5x to both sides)
-y = -5 - 5x
Multiplying by -1
y = 5x + 5
Both equations look the same so they are coincident. They have the same intercept y=5 and the same slope m=5.
No, you can only use the Pythagorean theorem on right triangles.
