Which ordered pair is valid for the graph of y = 3x + 2?
(-2, 8)
(2, 8)
(2,-8)

The answer is (2, 8

Step-by-step explanation:

Trace your finger (or cursor) along the x-axis to -2 for example then trace it up to 8 on the y-axis. If it's not along the line, then move on until you have a ordered pair that falls on the line.

i dont know sorry

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
