Question

Which equation is in point-slope form and depicts the equation of this line?

a. (y+4)=-1/3(x+1)
b. (y-1)=-1/3(x-2)
c. (y-4)=-5/3(x-1)
d.(y+4)=5/3(x+1)

Answer 1

that's a -4

Answer 2

You can compute the slope of the line by \(\frac{\Delta y}{\Delta x}\). What do you obtain?

Answer 3

If you get the slope of the line, you can eliminate two of the four options.

Answer 4

Pick one of the point and substitute in the given equations. The one where r.h.s = l.h.s is the correct equation

Answer 5

Btw the slope here is positive. The only equation with positive slope is d
