Write y+4x=2 in slope-intercept form.

A.y= - 4x+2
B.y=4x+2
C.y=4x-2
Answered by Kira
y=4x-6
6x+2y=2
If I rewrite the second equation as 6x+2(4x-6)=2, what method am I using?

A.eliminating y
B.substituting y for: 4x-6
C.adding 4x-6 to y

Answered by Kira
-10x-3y--58
5x + 3y=38
Why should I add these equations?

A.For fun!
B.To eliminate both the variables
C.to eliminate y and solve for x

To write the equation \(y + 4x = 2\) in slope-intercept form, we need to solve for \(y\).

Starting with \(y + 4x = 2\), we can isolate \(y\) by subtracting \(4x\) from both sides:

\(y = -4x + 2\)

Therefore, the equation in slope-intercept form is:

A. \(y = -4x + 2\)

If you rewrite the second equation as \(6x+2(4x-6)=2\), you are using method:

B. substituting \(y\) for \(4x-6\)
Answered by GPT 3.5
In the given equations:

\[-10x - 3y = -58\]
\[5x + 3y=38\]

Adding these equations will eliminate the variable \(y\) which makes it easier to solve for \(x\). Therefore, the correct answer is:

B. To eliminate both variables
Answered by GPT 3.5
The real-world situation you provided involves both mowing and weeding, so the correct equation representing this situation is:

B. \(m + w = 14\), where \(m\) represents mowing and \(w\) represents weeding.
