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

y= mx+ b

y= -2x +b

Put in (3,6) and solve for b. Then you know m and b in

y=mx + b

won't it be..0??

I think it will be zero.

Are you a teacher?

The question is

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

Let's test it.

Using y=mx+b with m=-2 and (3,6)

6=-2*3+b or

6=-6+b

If b=0, the we have

6=-6+0=-6 ??

Nope, not 0. Try 6+6=b

so it's 12??

Well if you have slope of -2 and the point is (3,6), then using

y=mx+b or

y=-2x+12

then substitute x=3 to get

y=-2*3+12=6

so yes, the y intercept is 12.
