Answer:

Part A)
y+2=(4)/(3)(x-3) ----> y plus
2 equals four thirds times the quantity x minus
3 end of quantity

Part B)
-4x+3y=-18 ---> negative
4x plus
3y equals negative eighteen

The answer is the option D

Step-by-step explanation:

Part A) we know that

The equation of a line into point slope for is equal to


y-y1=m(x-x1)

Find the slope

The formula to calculate the slope between two points is equal to



m=(y2-y1)/(x2-x1)


we have



A(3,-2)\ B(6,2)


Substitute the values



m=(2+2)/(6-3)


m=(4)/(3)

With the slope m and the point A find the equation of the line


y+2=(4)/(3)(x-3) -----> equation of the line into point slope form

Part B) we know that

The equation of the line into standard form is equal to


Ax+By=C

we have


y-2=(4)/(3)(x-6) ------> convert to standard form


y=(4)/(3)x-8+2


y=(4)/(3)x-6

Multiply by
3 both sides


3y=4x-18


-4x+3y=-18 ----> equation of the line in standard form

(y-y_1)/(x-x_1) = (y_2-y_1)/(x_2-x_1) \\ (y-(-2))/(x-3) = (2-(-2))/(6-3) \\ (y+2)/(x-3) = (2+2)/(6-3) \\ (y+2)/(x-3) = (4)/(3) \\ y+2= (4)/(3) (x-3)
In standard form

y+2= (4)/(3) (x-3) \\ 3(y+2)=4(x-3) \\ 3y+6=4x-12 \\ -4x+3y=-18
