Question

What is the equation of the line between `(73,13)` and `(94,4))`?

Answer 1

`color(green)(3x + y = 310 " is the standard form of equation"`

Explanation:

`(x_1, y_1) = (73,13), (x_2, y_2) = (94,4)`

`color(red)("Equation of the line is " (y-y_1)/(y_2-y_1) = (x-x_1) / (x_2-x_1)`

`(y - 13)/(4-13) = (x - 73)/(94-73)`

`((y-13) / -cancel(9)^color(red)(3)) =( (x-73)/ cancel(21)^color(red)(7))`

`y - 91 = -3x + 219`

`color(green)(3x + y = 310 " is the standard form of equation"`
