SOLUTION: Find slope if it exists. x +2y = 4 I subtract x from both sides 2y = 4 - x I then divide by 2 y= - 2 Is this correct? I divided both sides by -2: 2y/2 = 4-x/2

Question 352409: Find slope if it exists. x +2y = 4
I subtract x from both sides
2y = 4 - x
I then divide by 2
y= - 2
Is this correct? I divided both sides by -2: 2y/2 = 4-x/2

x%2B2y=4 Start with the given equation.


2y=4-x Subtract x from both sides.


2y=-x%2B4 Rearrange the terms.


y=%28-x%2B4%29%2F%282%29 Divide both sides by 2 to isolate y.


y=%28%28-1%29%2F%282%29%29x%2B%284%29%2F%282%29 Break up the fraction.


y=-%281%2F2%29x%2B2 Reduce.


So the equation y=-%281%2F2%29x%2B2 is now in slope intercept form y=mx%2Bb where the slope is m=-1%2F2 and the y-intercept is b=2 note: the y-intercept is the point
