Question

Find the missing coordinate to complete the ordered pair solution to the given linear equation.
2y+5x=-10
A. (-2,__)
B. (__,5)

Answer 1

@jim_thompson5910 Can you please help me
I'm sure I will have more after this I just want to make sure I know what I am doing.

Answer 2

A)

The ordered pair (-2, ___) means that we know for sure that x = -2

So plug in x = -2 and solve for y

2y+5x=-10

2y+5(-2)=-10

2y-10=-10

2y-10+10=-10+10 ... Add 10 to both sides.

2y+0= 0

2y = 0

y = 0/2

y = 0

So if x = -2, then y = 0

Therefore, (-2,___) turns into (-2,0)

Answer 3

I believe its A. (-2,0) and B. (-4,5)

Answer 4

B)

2y+5x=-10

2(5)+5x=-10

10+5x = -10

5x = -10-10

5x = -20

x = -20/5

x = -4

So the other ordered pair is (-4,5)

You are correct on both parts. Nice job.

Answer 5

Great!! Thank you. I'm sure I will have more haha. I just like to verify things

Answer 6

It looks like you definitely know what you're doing, which is great. Keep up the good work.
