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

1 Answer

2x+y-7=0

Explanation:

You can find the slope, m, of the line first.
m=(y_2-y_1)/(x_2-x_1)
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;
(y-y_1)=m(x-x_1)
(y-5)=-2(x-1)
y-5=-2x+2
SO the equation is 2x+y-7=0
