Question

Write a equation that will represent the information.

Answer 1

consider r to be x. and t to be y

`consider : (0, 5) \: and \: (1, 3) \\ gradient = ((3 - 5))/((1 - 0)) \\ = - 2 \\ y = mx + c \\ consinder : (1, 3) \\ 3 = ( - 2 * 1) + c \\ c = 5 \\ therefore : equation \: is \\ = > y + 2x - 5 = 0`
