4x + 8y = 16
3x + 6y = 9

Answer 1

Are the lines parallel?

Answer 2

That is...do they have the same slope?

Answer 3

its no sulotion

Answer 4

yes. you are correct. Good for you!

Answer 5

but i still need to work it out and i have no idea how

Answer 6

Solve both equations for y.

Answer 7

subtract?

Answer 8

That is slope-intercept form. Then you will be able to see that they have the same slope but different y intercepts and are therefore parallel.

Answer 9

im horrible at thiese

Answer 10
