Please answer number 7 I will give you brainliest, 5 stars, and a thanks! Plus ten points please answer quickly

it's by 3.  the scale factor decreases by 3.  

Step-by-step explanation: the " ' " indicates that that is the new coordinate example " p' " is the new coordinate for "P" same with Q and R.  On the y-axis is shows P going from 3 to 1 and that is saying 3/1.  3/1 is 3 which indicates that the scale factor is decreasing by 3.

step-by-step explanation:

a, b, c, d are correct.

step-by-step explanation:

we have g(x) = 3 and are required to find which option is a translation of g(x).

now, 'translation' is a transformation which means to shift the function in any direction and the general form of translation is g(x) + k, where k is any real number.

so, according to the options we see that all are correct as they satisfy the general form of translation.

also, it can be seen from the graph below that the function g(x) = 3 is shifted from its position in all the four options.
