NEED to Explain with numbers words and variables. There is a lot of pics so flip to each one and answer. I gave the choice and answer & Explain Brainleist Answer!

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4

answer: they are supplementary angles

step-by-step explanation: 161+19=180. supplementary angles equal 180 degrees

isn't it a pentagon? sense [3 (triangle) + 4 (rectangle)] - 2 (triangle and rectangle connected) = 5 (pentagon)
