what is the slope-intercept equation of the line that passes through the point (4, -6) and is parallel to y = -x + 5?

Question

Do u have any idea how to do this??

anonymous · Answer

supossed to say y=-1/2x+5 sorry :p

anonymous · Answer

I wouldn't know where to begin

angela210793 · Answer

the slope of the line, perpendicular to the one you're given is 
$$slope=-1/m$$ (m is the slope of the line ur given)

do u know what is the slope of y=-x+5?

anonymous · Answer

yes we are given the equation y=-1/2x+5 and using point slope which I belive is y=mx+b then according to that 1/2 would be the slope

angela210793 · Answer

ur almost right..the slope is -1/2(negative 1/2)

so the slope of the line ur trying to find is -1/(-1/2)=2

the equation of the line when ur given the slope and a point is :$$y-y0=m(x-x0)$$

angela210793 · Answer

x0=4 and y0=-6....can u do the substituition???

anonymous · Answer

D: what am I substituting for?
