Question

Identify the correct slope and y-intercept of the equation 2x + 4y = 8.
@AriPotta I'm sorry Harry... can you just explain this to me? I know the Y and X axis already.
y = (0,4) x = (2,0)

Answer 1

lol Luis.

Answer 2

rearrange the stuff to make it in slope-intercept form. so like, subtract 2x from both sides and then divide 4 from both sides

Answer 3

then you can see the slope clearly

Answer 4

or you could use the slope formula using those points

Answer 5

First you need to solve for y


\[\Large 2x + 4y = 8\]


\[\Large 4y = -2x + 8\]


\[\Large y = \frac{-2x + 8}{4}\]


\[\Large y = \frac{-2x}{4} + \frac{8}{4}\]


\[\Large y = -\frac{1}{2}x + 2\]


The equation is now in y = mx + b form. This is slope-intercept form.


In this case, m = -1/2 and b = 2


So the slope is -1/2 and the y-intercept as a point is (0, 2)

Answer 6

Ohh, I see.... Thank you all C;

Answer 7

'like' yeah. ;)
Yes, I do get it... just a little rusty on slope. I did module 4 way back when and now I'm retaking the exam so.
