Question

Write an equation in point slope form of the line passes through the point (9,0) and has a slope of m=-3

Answer 1

`\huge y = - 3(x - 9)`

Explanation:

To find an equation of a line in point slope form when given the slope and a point we use the formula

`y - y_1 = m(x - x_1)`

From the question we have the final answer as

`y - 0 = - 3(x - 9) \\ \\ \\ y = - 3(x - 9)`

Hope this helps you
