What is the equation of a line through the points (0, 9) and (3, 0)?

Equation of line passing through two given points (0,9) and (3,0) is

y = -3x + 9

Step-by-step explanation:

Given : Two points of line as (0,9) and (3,0)

We have to find the equation of line passing through two given points .

The general form of an equation of line is given by y = mx + c where m is slope and c is y intercept.

Slope between two points is given by formula,

Put m = -3 in equation y = mx + c

we get ,

Put (0, 9) in above equation , x= 0 and y = 9

we have,

Simplify, we get, c = 9

Thus, equation of line passing through two given points (0,9) and (3,0) is y = -3x + 9
