Point-Slope Form: y - y1 = m(x - x1) m: slope y1: y-coordinate of a point x1: x-coordinate of the same point

Each of the graphs below represents a line of best fit derived from some data. Match each definition below to the linear model it describes.

y - 7 = - .5(x + 4)

1

A

graph of a line passing through (-5, 1) and (3, -1)

y + 3 = - 4(x - 2)

2

B

graph of a line passing through (-4, 7) and (2, 4)

y + 5 = - 0.25(x - 1)

3

C

graph of a line passing through (-5, -1) and (2.5, 2)

y - 7 = 2(x - 4)

4

D

graph of a line passing through (-2, -5) and (4, 7)

y + 5 = 0.4(x + 1)

5

E

graph of a line passing through (-1, 9) and (2, -3)
