Question

Lee's distance from his friend's house over time is recorded in this table. Time in minutes (x) 0 2 6 12 16 Distance in miles (y) 8 7 5 2 0 Which equation represents this situation? y=−12x+16 y=−12x+8 y=−2x+16 y=−2x+8

Answer 1

slope = (y2-y1)/(x2-x1)

= (8-7)/(0-2)

=1/-2

m=-1/2

y-y1 = m(x-x1)

y-8 = -1/2(x-0)

y-8 = -1/2 x

y = -1/2x +8
