picture is the graph for the equation The graph shows the heights, y (In centimeters), of a plant after a certain number of weeks, X. Shania drew the line of best fit on the graph. What would most likely be the approximate height of the plant after 7 weeks? (1 point)
O 5.2 centimeters
O 7.6 centimeters 8.7 centimeters
O 12.7 centimeters
O 8.7 centimeters

3; 9 is 8 to -4

step-by-step explanation:

a

step-by-step explanation:

given the 2 equations

- x + y = - 2 → (1)

2x - 3y = 4 → (2)

multiplying (1) by 2 and adding to (2) will eliminate the x- term

- 2x + 2y = - 4 → (3)

add (2) and (3) term by term

(2x - 2x) + (- 3y + 2y) = (4 - 4), simplifying gives

- y = 0 ⇒ y = 0

substitute y = 0 in either of the 2 equations for corresponding value of x

substituting in (2) gives

2x = 4 ( divide both sides by 2 )

x = 2

solution is (2, 0 ) → a

15 / 2 = 7.5

100 / 7.5 = 13.
