Have to finish before I slep

2) option 2

3) option 3

4) option 4

Step-by-step explanation:

2) sqrt[(3-2)² + (2-0)²]

= sqrt(1+4)

= sqrt(5)

3) Mp = (x1+x2)/2, (y1+y2)/2

= (-1+1)/2 , (0+2)/2

4) (7+9)/2, (4-1)/2

16/2 , 3/2

(8, 3/2)

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
