Answer: y=(1/2)x + 2
Slope intercept form: y = mx + b
y= answer, y-value
m=slope
x= independent variable, x-value
b= y-intercept (0,b)
x-2y=4
1. Isolate 2y by adding x to both sides of the equation: 2y = 4+x
2. Isolate y by dividing 2 to both sides of the equation: y = 2+(1/2)x
3. Rearrange in slope intercept form.
y=(1/2)x + 2
