Sarah enjoys running through the neighborhood. She follows the route marked on the map below starting and ending at her house. Find the distance in feet that Sarah runs

a reflection across the x-axis , followed by the by a reflection across the y-axis , and then a scale dilation of 0.5 .

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
