Which equation shows 2x – y = 6 converted to slope-intercept form?
2 answers:
The general equation for slope-intercept form is y = mx + b, where m = the slope of the equation, b = the y intercept, and x and y are your variables (and the coordinate points on the graph).
To get 2x - y = 6 into slope intercept form, you want a positive y on one side of the equal sign, and x and your y intercept/constant on the other side of the equal sign.
1) Add y to both sides of the equation to get a positive y:
2) Subtract six from both sides of the equation to get y by itself on one side of the equal sign:
The equation in slope-intercept form is: y = 2x - 6

Hello!
Let's write some important information contained in the exercise:
• hotdogs: $2.59 (,x,)
,• hamburgers: $5.29 (,y,)
He needs 11 packages. Let's write it:
• x + y = 11
He spent a total of $39.29. We can write it as:
• 2.59x + 5.29y = 39.29
Now, let's solve these two equations as a linear system:
First, let's isolate x in equation A:
Now, we will replace where's x by 11-y in equation B:
As I called the hamburgers as 'y', we know that he bought 4 packages of hamburgers.
