Answer:
Point Slope Form: y + 9 = -1/3(x - 3)
Slope-Intercept: y = -1/3x - 8
Step-by-step explanation:
<u>Point Slope Form: (y - y1) = m(x - x1)</u>
<u>Slope-intercept Form: y = mx + b</u>
<u>Step 1: Use point slope form</u>
(y - (-9)) = -1/3(x - 3)
Answer: Point Slope Form: y + 9 = -1/3(x - 3)
Step 2: Use point slope to get slope intercept
y + 9 = -1/3(x - 3)
y + 9 - 9 = -1/3x + 1 - 9
y = -1/3x - 8
Answer: Slope-Intercept: y = -1/3x - 8
