Question

Write the equation (use any form you choose) of the line that passes through the points (4, 3) and (-2, 6)

Answer 1

gradient

`m = (y - y)/(x - x) \\ m = (6 - 3)/( - 2 - 4) \\ m = ( - 1)/(2)`

`equation \\ y = mx + c \\ 3 = ( - 1)/(2) *(4) + c \\ 3 = - 2 + c \\ c =5`


THE ANSWER IS :-

`y = mx + c \\ y = - (1)/(2) x + 5`
