which equation is the point-slope equation of the line that passes through the points (-2,-1) and (7,-4)?

B (for question 7)

Step-by-step explanation:

To find the slope, we use the equation .

m = (-4+1)/(7+2) = -3/9 = -1/3

Since B is the only option that would give a slope of -1/3, B must be the answer.

(you can use this same method for question 8)

answer: idk

step-by-step explanation:

10/60

step-by-step explanation:

if you divide 10 by 60 the answer is 0.166666 while if you divide or solve the other problems it equals 0.6
