Question

y varies jointly with p and q. When p = 12 and q = 4, y = 144. Find y when p = 10 and q = 6.

Answer 1

\[Slope = \frac{y_2 - y_1}{x_2 - x_1}\]

Use this formula:

Here, (x1, y1) = (1, 4) and (x2, y2) = (1, -3)..
Plug in the values and find the slope..

Answer 2

here is the formula
\[m=y2-y1/x2-x1\]

Answer 3
