Aline that includes the points (7,u) and (6,6) has a slope of -8. what is the value of u?

(6-u)/(6-7)= (6-u)/-1= 8

6 - u = -8

-u = -14

u = 14

u = - 2

Step-by-step explanation:

Slope = change in value of y on the vertical axis / change in value of x on the horizontal axis

change in the value of y = y2 - y1

Change in value of x = x2 -x1

y2 = final value of y

y 1 = initial value of y

x2 = final value of x

x1 = initial value of x

From the information given,

Slope = - 8

y2 = 6

y1 = u

x2 = 6

x1 = 7

Therefore,

- 8 = (6 - u)/(6 - 7)

- 8 = (6 - u)/ - 1

6 - u = 8

u = 6 - 8 = - 2

i don't see any steps below, sweetheart

so first lets findout how much she spent so whats 32.00 - x = 9.20

32.00 - 22.75 =9.25. so she spent a total of $22.75 okay now we know the amount she spent. so now u got it from here.
