Write the equation of the line that passes through each pair of point (1,2) (-1,-3)

Sagot :

Answer: y = 3

Step-by-step explanation:  

So, we must find an equation of a line that passes through these two points such that we find the slope first as,  

m = (3-3) / (2-(-1)) = 0 / 3 = 0. Then we bring up the point-slope form of an equation to find the line such that  

y - y1 = m(x - x1). Next,  

y - 3 = 0(x - (-1))

y - 3 = 0..............Then add 3 such that the equation of a line is
