potatoes.ramu · Answer

We know that y=1 and x=-2

ganeshie8 · Answer

hint : if a line has slope of $m$, then the line perpendicular to it will have a slope of $\large  -\frac{1}{m}$

potatoes.ramu · Answer

Satisfies the equation of the line WX

ganeshie8 · Answer

so, start by finding the $slope$ of given line from the graph

ganeshie8 · Answer

knw how to find the $slope$ form the graph ?

potatoes.ramu · Answer

Or.. find the coordinates of W and X from the graph first to calculate the slope of WX

potatoes.ramu · Answer

You can find the slope using the formula after that :)

potatoes.ramu · Answer

In this case, the coordinates of X are (4,3) and Y are (-4,-1).. Can you find the slope now.. @Starr_DynastyT

anonymous · Answer

ok @Potatoes.ramu im getting that it would be -2

potatoes.ramu · Answer

It's 2. The minus signs cancel :)

anonymous · Answer

so i just have 2 find the second part

potatoes.ramu · Answer

So that means the slope of the line perpendicular to this will have a slope of -1/2 :)

potatoes.ramu · Answer

So that means only the third equation in those options satisfies this condition :) Use the standard equation y=mx+c.. where m=slope.

anonymous · Answer

so C would be th answer the 2 positive but into 1/2

potatoes.ramu · Answer

Yeah! C is the answer! Did you understand how we got here? :)

anonymous · Answer

yes i believe so the first part narrowed it down

potatoes.ramu · Answer

good! :) Best of luck! :)
