I NEED HELP ASAP (NO links, I need real answers)

Step-by-step explanation:

for the first one:

first find the original slope from the given points using the equation:

y2-y1 / x2-x1

x1= 7  y1=4

x2=-2    y2=10

(the coordinates can be either 1 or 2 they just have to correspond with their other value)

now we solve

10-4 / -2-7

6 / -9

2 / -3=k

now we multiply by the factor of 1/2

(dialated means that the 1/2 value actually equals 2 since it would be considered b (b is 1/b in the equation) and 1/ 1/2 is 2)

2/-3 *2/1

4/-3

for problem 2:

to find the scale value we would need to divide the new value of x by the original value which would be

QR/NP

problem 3:

to find the scale factor use the points plotted and the equation previously mentioned

F (1,9) E (-7,-3) B(-1,-2) C(3,4)

-7*1 / -1*3

-7/-3 is the scale factor
