What is slope and y intercept of 5x-10y=20?
2 Answers
The slope is
Explanation:
First, you get y by itself. That gives you -10y=-5x+20. Then you divide both sides by -10. That gives you y=1/2x-2. The slope is the number with the variable and the y intercept is the other number.
Mathematical explanation
5x-10y=20 -10y=-5x+20 (-10y)/(-10)=(-5x)/(-10)+20/(-10) y=(5/10)x-2 y=1/2x-2
Now recall the format
From our equation,
y-intercept
Explanation:
Given:
Before we do anything else notice that all the value are exactly divisible by 5 so lets simplify.
Divide everything by 5
To make the
Add
Divide both sides by 2
Change the order to match convention
