Question

What is the equation in the point-slope form of the line that passes through the point (-1,-4) and has a slope of -3?

Answer 1

Answer:

y=mx+b;  y=-3x+-4

Step-by-step explanation:

Substitute the slope, and the y-intercept in place of m and b

Answer 2

Answer: $(y+4)=-3(x+1)$

Step-by-step explanation:

We know that the equation a line in point-slope form having slope m and passing through point (a,b) is given by :-

$(y-b)=m(x-a)$

Then , the equation a line in point-slope form having slope '-3' and passing through point (-1,-4) is given by :-

$(y-(-4))=-3(x-(-1))\\\\\Righarrow\ (y+4)=-3(x+1)$
