what is the point-slope equation of the line with a slope of -1/3 line that goes through the point (4,-5)
answers
y-5=1/3(x+4)
y+5=1/3(x-4)
y+5=-1/3(x-4)
y-5=-1/3(x+4)
We can eliminate A and B already since the slope is -1/3. To check to see which works do I do a test point with (0,0)?

no just write 
$$y-y_1=m(x-x_1)$$ which for you is 
$$y-(-5)=-\frac{1}{3}(x-4)$$

misty1212 · Answer

the only tiny sophistication here is that $(--(-5)=+5$

misty1212 · Answer

actually i meant $-(-5)=+5$  go with C
