Answer:
3,3/2
Step-by-step explanation:
let 10,-6 be x1, y1
-4,-9 be x2, y2
(x1+x2)/2 , (y1+y2)/2
(10-4)/2 , (-6+9)/2
6/2 , 3/2
3 , 3/2
-10(s + 1) = -87
The same way you do positive numbers, you do negative number. Multiply whatever is in the parenthesis by what's on the outside, which in this case is -10. So:
-10*s + -10*1 = -87
-10s + -10 = -87
To solve, first add -10 to both sides
-10s = -77
next, divide both sides by -10
s = 7.7
To check the answer, plug the solution into the original equation
-10(s+1) = -87
-10(7.7 + 1) = -87
-10(8.7) = -87
-87 = -87
(for the first one, is there a variable involved?)

Answer:
- 0.404 . . . cm/day
- the average growth per day in cm
Step-by-step explanation:
The slope is the x-coefficient in the equation, 0.404.
The slope is the rate of change of the dependent variable (height) with respect to the independent variable (number of days). In this case, it is the average increase in the plant's height each day, in cm.
