Find the equation of a line with a slope of 1 and passing through (11;3)

Step-by-step explanation:

slope(m)=(Y-Y1)/X-X1

here,

M=1

(X1,Y1)=(11,3)

NOW,

m=(Y-Y1)/(X-X1)

1=(Y-3)/(X-11)

1×(X-11)=Y-3

X-11=Y-3

X-Y-11+3=0

X-Y-8=0

X-Y=0 is the required equation.

  6 1/6 hours after 9 am, or 3 1/6 hours after noon

Step-by-step explanation:

If we count time (x) in hours after 9 am, the stock prices will be ...

  A = 16.15 +0.06x

  B = 16.90 -0.12(x -3)

The value of x when A = B can be found from ...

  A = B

  16.15 +0.06x = 16.90 -0.12(x -3)

  0.18x = 1.11 . . . . . . . . add 0.12x-16.15

  x = 6.16666...(repeating) = 6 1/6

6 1/6 hours after 9 am, the prices will be the same. That is 3 1/6 hours after noon.
