Slope = y2 - y1/x2 - x1
          = -3 - (-1)/8 - (-2)
          = -3 + 1/ 8 + 2
          = -2/ 6
          = - 1/3

hope this helps :)

Slope is rise/run so you need the difference between each x and y
-2 and 8 have 10 units between them
-1 and -3 have 2 units
y is the rise, and x is the run
so your slope is 2/10 or 1/5
it is negative because the line is going downward 
final answer is -1/5

The difference between the squares of two consecutive numbers is 23. what are the two numbers?
Ksju [112]

(x+1)^2-x^2=23

x^2+2x+1-x^2=23

2x+1=23

2x=22

x=11

11^2 = 121

x+1 =12

12^2=144

144-121 = 23

Evaluate -Z + 7.49 for Z = -7.1
luda_lava [24]
14.59

To solve, simply plug -7.1 into -Z. Since Z is negative in the equation, it will turn the Z that’s given to us into a negative. Since that Z is already negative, it will now become a positive since that’s what two negatives being multiplied make. This is what your problem will look like:

-(-7.1) + 7.49
7.1 + 7.49 = 14.59
