Answer:
no
Step-by-step explanation:
slope = (y2 - y1) / (x2 - x1)
(8,5)...x1 = 8 and y1 = 5
(-12,-9)....x2 = -12 and y2 = -9
now sub
slope(m) = (-9 - 5) / (-12 - 8) = - 14 / - 20 = 7/10
y = mx + b
slope(m) = 7/10
(8,5)...x = 8 and y = 5
sub and find b, the y int
5 = 7/10(8) + b
5 = 56/10 + b
5 - 56/10 = b
50/10 - 56/10 = b
-6/10 = b
- 3/5 = b
ur equation is : y = 7/10x - 3/5.....gonna put it in standard form now
y = 7/10x - 3/5 ....multiply everything by LCD of 10
10y = 7x - 6
-7x + 10y = -6
7x - 10y = 6
NO....7x - 10y = 3 IS NOT a good model....should be 7x - 10y = 6
