Question

write the equation of the line through the points (1, -1) and (3, 5) ​

Answer 1

Answer:

equation of line :-

x-1 = 3+1/5-1(y+1)

x-1 = 4/4(y+1)

x-1 = y+1

x-y = 2

Answer 2

Answer:

y-3x+4=0

Step-by-step explanation:

(x1,x2)  (y1,y2)

(y-y1) = y2-y1/x2-x1  (x-x1)

= y+1 = 5+1/ 3-1 (x-1)

=y+1 = 6/2 (x-1)

=y+1= 3(x-1)

=y+1= 3x-3

=y-3x+4=0
