Question

Help for medal?
Select the equation of the line that passes through the point (3, -1) and is parallel to the line on the graph.

Answer 1

y = -1

y = 3

y = x -1

y = 3x - 1

Answer 2

@aum Help?

Answer 3

How is the link you posted connected to this problem?

Answer 4

I'm not sure it was just with the question.

Answer 5

(3, -1) has a y value of -1. y = -1 is a horizontal line parallel to the x-axis. ANY point that has a y-value of -1 will be on this line. Therefore, (3,-1) will be on this line.

Try out other choices to see if there are any other lines that has (3,-1).
Put x = 3 and y = -1 in each equation to see if it is valid.

Answer 6

Would it be D?

Answer 7

y = 3x - 1
put x = 3 and y = -1
-1 = 3(3) - 1
LHS is -1 and RHS is 8. So the equation is not satisfied. So D is false.

Answer 8

Is it B?

Answer 9

No. (3,-1) has a y value of -1. In B, y = 3. It does not have a y-value of -1.

Answer 10

I don't see how it could be C then
