The point (5,4) and (X,8) lie on the same line. If the slope of the line is -2, what is the value of X? Show your work

x = 3

Step-by-step explanation:

calculate the slope using the slope formula and equate the result to - 2

m =

with (x₁, y₁ ) = (5, 4) and (x₂, y₂ ) = (x, 8)

m = = = - 2, thus

- 2(x - 5) = 4, that is

- 2x + 10 = 4 ( subtract 10 from both sides )

- 2x = - 6 ( divide both sides by - 2 )

x = 3

the red lines denote the population of the bacteria after 35 hours. that would be 2,409.24. the y-intercept is the blue line which is 800 because that is the starting point. the equation used to make the graph is 800(1.032)^h, where h is the number of hours.
