What is an equation of the line that passes through the points (-4,-3) and (3,-3)
agasfer [191]

Answer: y=-3

Explanation:

Equation of a line that passes through (a,b) and (c,d) is given by :-

(y-b)=\dfrac{d-b}{c-a}(x-a)

The equation of the line that passes through the points (-4,-3) and (3,-3) :

(y-(-3))=\dfrac{-3-(-3)}{3-(-4)} (x-3)\\\\\Righatrrow\ (y+3)=\dfrac{0}{7}(x-3)\\\\\Rightarrow\ y+3=0\\\\\Rightarrow\ y=-3

Hence, the equation of the line that passes through the points (-4,-3) and (3,-3) : y=-3
