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

Answer 1

Well, do you know what slope intercept form entails?

Answer 2

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..

Answer 3

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

Answer 4

Knowing this, we can start ruling out some answers

Answer 5

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

Answer 6

y = -one halfx + 2

Answer 7

Yes, that is written in slope intercept form

Answer 8

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

Answer 9

yeah

Answer 10

then there you go! Congrats!
