What is the equation of the line that passes through the following points?: (2,3),(1,5),

1 Answer

2x+y7=0

Explanation:

You can find the slope, m, of the line first.
m=y2y1x2x1
So slope=2
Then you can find the equation; you can choose any point you like, I choose (1,5).
The equation is given by;
(yy1)=m(xx1)
(y5)=2(x1)
y5=2x+2
SO the equation is 2x+y7=0
