Write the equation of a line with the slope of -2 which contains the point (3,6)

The x-axis has 0 slope. What about any other line with 0 slope?

Use y-y1=m(x-x1) with m=-2, x1=3 and y1=6

What??

These were your questions and my responses.

Q1

What type of lines have a slope of zero?

A1

The x-axis has 0 slope. What about any other line with 0 slope?

Comment:Wouldn't it be parallel to the x-axis?

Q2

Write the equation of a line with the slope of -2 which contains the point (3,6)

A2

Use y-y1=m(x-x1) with m=-2, x1=3 and y1=6

Comment:Does this formula look familar?

Now what is your question?

so wait for number 1 would it be parrallel lines and for number 2 it still looks confusing!!

Yes, 1 is lines parallel to the x-axis.

2. wants you to use the point slope form for the line. You're asked

Write the equation of a line with the slope of -2 which contains the point (3,6)

y-6=-2(x-3) or y=-2x +12

-2 is the slope and 12 is the y intercept. As a check substitute 3 for x to get y=-2*3+12=6 which is true.
