Question

given the points (0,-1) and (-6,-7) and on a line, find its equation in the form y= mx+b y=_______

Answer 1

y = -x - 1

EXPLANATION :

Using the two-point formula :

`y-y_1=(y_2-y_1)/(x_2-x_1)(x-x_1)`

From the problem, the two points are (0, -1) and (-6, -7)

`\begin{gathered} y-(-1)=(-7-(-1))/(-6-0)(x-0) \\ y+1=(-6)/(-6)(x) \\ y+1=-x \\ y=-x-1 \end{gathered}`
