Use a graphing calculator to find an equation of the line of best fit for the data. Round the slope to the nearest tenth and the y-intercept to the nearest integer. x -15,-10,-5,0,5,10,15,20
y -4,2,7,16,22,30,37,43
y = ___
Identify the correlation coefficient. Round to the nearest thousandth.
r = ___

im pretty sure it would be 5 am, hope that , and give brainliest and guys if this is right then press the button and give 5 stars

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
