-4(r+6)=-63

first: substitute -4 to the brackets (r+6)

-4r - 24 = - 63

add 24 to both sides

-4r - 24 + 24 = -63 + 24

simplify

-4r = -39

divide both sides by -4

r = 9.75

hope that helps

-4r-24=-63
-4r=-63+24

The table shows a linear function.

Answer:

$\large\boxed{y=\dfrac{5}{3}x+9}$

Step-by-step explanation:

The slope-intercept form of an equation of a line:

$y=mx+b$

m - slope

b - y-intercept → (0, b)

The formula of a slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

From the table we have an y-intercept (0, 9) → b = 9.

Take other point from the table (-6, -1).

Calculate the slope:

$m=\dfrac{-1-9}{-6-0}=\dfrac{-10}{-6}=\dfrac{5}{3}$

Finally:

$y=\dfrac{5}{3}x+9$
