Answer 1

First we need to find the equation, so we need to calculate the slope

`m=(y_2-y_1)/(x_2-x_1)`

where

(5,30)=(x1,y1)

(10,0)=(x2,y2)

these points are part of the line

`m=(0-30)/(10-5)=(-30)/(5)=-6`

then we need the y-intercept, in this case, is when the value of B when t is 0

in our case is 60

therefore the equation is

`B=-6t+60`

the slope as we calculate previously is -6 which revels
