What are the slope and y-intercept of the line represented by the points shown in the table? slope: 2, y-intercept: –20 slope: 2, y-intercept: 10 slope: 5, y-intercept: –20 slope: 5, y-intercept: 10

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

i believe it's a.

i'm not sure on this one, most likely correct.

2: 10

step-by-step explanation:

answer: a

step-by-step explanation: the answer is a due to the rule of symmetry; that a line of symmetry must divide a figure into 2 pieces that are the exact same, only reflected over a line of symmetry. b and c do not have lines of symmetry and would not divide the figure evenly, thus making the answer a.
