Hours worked 2 4 5 8
Amount paid ($) 30.40 60.80 76 121.60











A.










B.










C.










D.

Answer 1

x1 -x = 4 - 2
x1 - x = 2
x2 - x1 = 5-4
x2 - x1 = 1
y1 - y = 60.80 - 30.40
y1 - y = 30.40
y2 - y1 = 76 - 60.80
y2 - y1 = 15.2
slope = y2-y1/x2-x1
m= 15.20/1
using point slope form
y - y2 = m(x - x2)
y - 5 = 15.20(x - 76)
y = 15.2x - 1155.20 +5
y = 15.2x - 1150.2
