Which of the following equations is written in slope-intercept form?
2x + 4y = 8
4y = -2x + 8
y = -one halfx + 2
x = -2y + 4

Question

Which of the following equations is written in slope-intercept form?
2x + 4y = 8
4y = -2x + 8
y = -one halfx + 2
x = -2y + 4

anonymous · Answer

Well, do you know what slope intercept form entails?

anonymous · Answer

slope-intercept form is 

y= mx +c  

i.e. the equation must be in form where y is on one side with a coefficient of one..

anonymous · Answer

It is usually written as y= mx+b, where m is the slope and b is a constant number

anonymous · Answer

Knowing this, we can start ruling out some answers

anonymous · Answer

2x+4y=8 is not the proper form, so we can rule it out. Same thing applies for x=-2y+4

anonymous · Answer

y = -one halfx + 2

anonymous · Answer

Yes, that is written in slope intercept form

anonymous · Answer

Do you understand why 4y= -2x+8 is not the correct answer?

anonymous · Answer

yeah

then there you go! Congrats!
