slope intercept form of the equation (-1,0) and (0,-1)

Question

i need help!!

Answer 1

Start by finding the slope 

 

m=(y2 - y1)/x2 - x1)=(-1 - 0) / (0 - -1) = (-1)/(+1)=-1

 

The y-intercept is -1, because (0,-1) is given as one of the two points.

 

Your line, in S-I form is therefore y=-x-1.

 

Check the answer:

0=-(-1)-1 YES

-1=-(0)-1 YES
