Answer 1

A. I will not show all the solutions for the equation, because that's impossible, being that the line is endless and goes infinitely to both (opposite to each other) directions.

To find any point, plug in the x value and solve for y.
for example
\[9x-y=-2\]plug in 2 for X,
so,\[9(2)-y=-2\]\[18-y=-2\]\[-y=-20\]\[y=20\]so your point would be\[(2,20)\]

any point on the line is a solution, plug in x values and find the coordinates just like I did above.

Answer 2

any x values?

Answer 3

you choose any random number and say x= seomthing

plug in that number for y and there will be your coordinate.


See how I did it with x=2 ?

Answer 4

I graphed it and its not infinite?

Answer 5

I don;t even know what to say. I can't be explaining why is a line endless? the graph doesn't stop at those 2 points it goes both directions endlessly.

If you don't know this, then i can't farther help.

Answer 6

the line is infinite but i meant, i can just pick any x value?

Answer 7

yes, any x value, it should give you the y value too.

the x value and y value you get is going to be one of the coordinates of the line, (no matter what you choose for x)

Answer 8

okk ty

Answer 9

what about part C

Answer 10

The must be parallel to be inconsistent, this way they never intersect, and therefore have no solution.

it can be any equation with the same slope no matter what the y-intercept is.

Answer 11

could you write one as an example? :0

Answer 12

@SolomonZelman

Answer 13

\[9x-y=-2~~~~~~~~~~~->~~~~~~~-y=-9x-2~~~~~~~~~->~~~~~~~~~~y=9x+2\]
Inconsistent equation would be.\[y=9x-3\]

Answer 14

Ohh!! Ty!!

Answer 15

You welcome!
