Which pair is a solution of
2y=6+3x ?

a. (-1, 1 and 1/2)

b. (-1, 9/2)

c. (-1, 3)

d. (3, 2)

Only way I know of to solve this is trial and error. You have to run through all of them to get the right pair :P

(x, y)

Let's try choice A.

2(1.5) = 6 + 3(-1).

3 = 6 + (-3).

3 = 6-3.

3 = 3.

WHOA! We got it on the first try!

Therefore, choice A is a solution for 2y = 6 + 3x

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17
