Both 17/10 and 2 4/5 should be rounded up in preparation for this estimation.
17/10 is close to 2 and 2 4/5 is close to 3. Thus, your estimated answer should be
2/3, or approx. 0.6666....
Exact answer: divide 17/10 by 14/5. LCD is 10, so convert 14/5 to 28/10.
Now divide 17/10 by 28/10. Answer: 17/28 = approx. = 0.607 approx.
These two results are comparable: 0.6666.... and 0.6071 ....
I’m not sure I understand your question
(-6,4) and (3, 1)
slope =(4-1)/(-6-3) = -3/9 = -1/3
equations
y - 4 = -1/3(x + 6)
y - 1 = -1/3(x - 3)
answer C and F
C. y - 1 = -1/3(x - 3)
F. y - 4 = -1/3(x + 6)
