Question

a line with a slope of -1/9 passes through point (9,-1). What is its equation in slope intercept form

Answer 1

`\huge \orange{y = - (1)/(9) x} \\`

Explanation:

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

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

From the question we have

`y + 1 = - (1)/(9) (x - 9) \\ y + 1 = - (1)/(9) x + 1 \\ y = - (1)/(9) x + 1 - 1`

We have the final answer as

`y = - (1)/(9) x \\`

Hope this helps you
