Question

which is an equation of the line passing through (3,9) with a slope -2/3?

Answer 1

point slope formula:
\[y-y_1=m(x-x_1)\]

Answer 2

\[y-9=-\frac{2}{3}(x-3)\]

Answer 3

o in understand now thanks so much!

Answer 4

Equation of line: y = mx + c.
m = 2/3 (known).
Plug in known point: 9 = (2/3) * 3 + c ==> solve for c.

Answer 5

(or m = -2/3. can't tell due to line break in your question)
