A

Step-by-step explanation:

Calculate the slope m using the slope formula

m =

with (x₁, y₁ ) = (6, a ) and (x₂, y₂ ) = (9, - 4 )

m = =

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

2x - 3y = 6 ( subtract 2x from both sides )

- 3y = - 2x + 6 ( divide through by - 3 )

y = x - 2 ← in slope- intercept form

with slope m =

Parallel lines have equal slopes , then

= , so

- 4 - a = 2 ( add 4 to both sides )

-a = 6 ( multiply both sides by - 1 )

a = - 6 → A

dc=6 square root of 3 and ac is 12 square root 3

c and d

step-by-step explanation:

square root of 3/2 = 18/c

cross multiply to get 18*2=√3*c

36/√3 * √3/√3 = c

c= 36*√3/3

c=12√3
