Given : 7y=8x-14 and y =6

We plug in 6 for y in the given equation

Statement                      Reason

7y=8x-14, y=6                  Given

7(6)= 8x-14                      Substitution

56 = 8x                          Add 14 on both sides

7 = x                               divide by 8 on both sides

Hence proved x=7

An image point has coordinates B'(7, -4). Find the coordinates of its pre-image if the translation used was (x + 4, y + 5).
Vera_Pavlovna [14]

Answer:

B

Step-by-step explanation:

B'(7, -4)

Let the pre-image coordinates be (x,y)

Consider x-coordinate,

x + 4 = 7

x = 3

Consider y-coordinates,

y + 5 = -4

y = -9

pre-image coordinates is (3, -9)
