Marla had a piece of felt that is 1/3 of a large circle. she cuts the piece of felt in half from the center point of the circle. what is the angle measure of each part?

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

thus, the first answer choice, y = sec x, is the correct one
