4x+8y=12 in slope intercept form?

y = -1/2 x + 3/2

Step-by-step explanation:

Solve for y.

4x + 8y = 12

8y = -4x + 12

y = -4/8 x + 12/8

y = -1/2 x + 3/2

step-by-step explanation:

we have three similar triangles, because each has a right angle and shares an angle.   let's write the angles in order: opposite to short leg, long leg, hypotenuse.

cab similar to bad similar to cbd

or as ratios,

ca: ab: cb = ba: ad: bd = cb: bd: cd

we also know

ac = ad + cd

(ad+cd): ab: cb = ba: ad: bd = cb: bd: cd

(ad+cd)/cb=cb/cd

we have cb=6, ad=5 and seek x=cd.

we reject the negative root and conclude x=4

answer: 4
