Question

What is y

Answer 1

Slope intercept form of a line

• y=mx+b

Now let's convert

#1

$\\ \sf\longmapsto 2x+y=2$

$\\ \sf\longmapsto y=-2x+2$

• m=-2
• b=2

#2

$\\ \sf\longmapsto x+2y=4$

$\\ \sf\longmapsto 2y=-x+4$

$\\ \sf\longmapsto y=\dfrac{-1}{2}x+2$

• m=-1/2
• b=4

#3

$\\ \sf\longmapsto 2x-y=2$

$\\ \sf\longmapsto y=2x-2$

• m=2
• b=-2

#4

$\\ \sf\longmapsto x-2y=4$

$\\ \sf\longmapsto 2y=x-4$

$\\ \sf\longmapsto y=1/2x-2$

• m=1/2
• b=-2

Answer 2

Step-by-step explanation:

Looks like you want all equations converted into slope-intercept form.

• 2x + y = 2 ⇒ y = -2x + 2
• x + 2y = 4 ⇒ 2y = - x + 4 ⇒ y = - 1/2x + 2
• 2x - y = 2  ⇒ y = 2x - 2
• x - 2y = 4  ⇒ 2y = x - 4 ⇒ y = 1/2x - 2
