Question

Indicate in standard form the equation of the line passing through the given points. A(4, 1), B(5, 2)

Answer 1

1 = 4m+b
2 = 5m+b

-1 = -4m-b
2 = 5m+b
------------
1 = m ; b= -3

Answer 2

-x + y = -3\

and since they dont like negative first terms .....

x - y = 3

Answer 3

thank you

Answer 4

would you be able to do it with other points?
