Question

There is a line that includes the point (18, 12) and has a slope of 1/9. What is its equation in slope intercept form

Answer 1

y = 1/9x +10

Explanation:

It is convenient to start with a version of point-slope form and simplify the result.

y = m(x -h) +k . . . . . line with slope m through point (h, k)

Using the given numbers, we have ...

y = (1/9)(x -18) +12

y = 1/9x -2 +12 . . . . . eliminate parentheses

y = 1/9x +10
