Follow the ax + by + c formula

ax = -3x (because both has x)
by =  y 
c =  7 (it is the constant)

-3x + y + 7 is your answer

follow the y = mx + b formula

2y = 6x + 12

2(y) = 2(x + 6)
y = x + 6 is your answer

hope this helps

Identify the scale factor when we scale up from Figure S to T. Just write the number.
Sergeu [11.5K]

Answer:

Scale factor = 4

Step-by-step explanation:

Scale factor = \frac{\text{Dimension of the image}}{\text{Dimension of preimage or original}}

Since, S is being dilated with a scale factor to form T,

So, the figure S is the preimage and figure T will be the image,

Length of one side of image T = 8

Length of one side of preimage = 2

Therefore, Scale factor = \frac{8}{2}

                                       = 4

Scale factor by which figure S has been dilated to form figure T is 4.
