Question

Write the equation for a line with a slope of -1 and going through point (4, 9). Write your answer in any form you like.

I appreciate any and all help. Thank you!

Answer 1

One form of the equation: y - 9 = -1(x - 4). In the Y intercept form: y = -x + 14.

Explanation:

Use the Point Slope form:

y - y1 = m(x - x1)

y - 9 = -1(x - 4)

y = -x + 5 + 9

y = -x + 14
