## anonymous 4 years ago Find the slope of the line whose equation is 2x 4y = 10. I had this question on one of my math quizzes and i got it wrong. i guessed -1/2 but the answer was just 1/2. what did i do wrong?

1. anonymous

neglected to put a sign between 2x and 4y

2. anonymous

- sorry

3. anonymous

1/2

4. anonymous

2x-4y=10

Always get it in the form y = mx + b and it's foolproof method.

To find the slope from an equation, the easiest way is to change it into slope-intercept form: y=mx+b $2x-4y=10$$-4y = 10-2x$$y = \frac{1}{2}x-\frac{5}{2}$The coefficient of x is 1/2, so that's your slope.

when you divided -2x by -4 you should have gotten 1/2x and 1/2 is the slope your signs must have been off
