(8,-4) y=-1/2x+11

I also have to do the same for this type and im stuck too

(-5,-6) x axis

**Damon**, Sunday, July 8, 2012 at 12:23amwrite given line as y = m x + b

y = (-1/2) x + 11

so m = slope = -1/2)

we need the same slope so our line is of form

y = (-1/2) x + b, but we need to find b

use given point to find b

-4 = (-1/2)8 + b

-4 = -4 + b

b = 0

so

y = (-1/2)x + 0 or -2 y = x

**Damon**, Sunday, July 8, 2012 at 12:25amslope of x axis is 0 so

y = 0 x + b

-6 = 0 (-5) + b

b = -6

so

y = -6

horizontal line six units below x axis
