Answer:

Step-by-step explanation:

A rate is a special ratio in which the two terms are in different units. For example, if a 12-ounce can of corn costs 69¢, the rate is 69¢ for 12 ounces. When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit rates.

$\qquad$ ☀️ $\pink{\bf{ {Answer = \: \: -2 }}}$

Let assume –

$\bf (x_1,y_1) = (t,-6)$
$\bf (x_2,y_2) = (-1,3)$

As we know – The slope formula is or the change in the y values over the change in the x values.

$\qquad$ $\pink{\twoheadrightarrow\bf Slope, m = \dfrac{y_2-y_1}{x_2-x_1}}$

<u>According to the question </u>–

$\qquad$ $\pink{\twoheadrightarrow\bf \dfrac{y_2-y_1}{x_2-x_1} = 9}$

$\qquad$ $\twoheadrightarrow\sf \dfrac{3 -(-6)}{-1-t}=9$

$\qquad$ $\twoheadrightarrow\sf \dfrac{3+6}{-1-t} = 9$

$\qquad$ $\twoheadrightarrow\sf \dfrac{9}{-1-t}=9$

$\qquad$ $\twoheadrightarrow\sf \dfrac{1}{-1-t} = \dfrac{9}{9}$

$\qquad$ $\twoheadrightarrow\sf \dfrac{1}{-1-t} =\cancel{ \dfrac{9}{9}}$

$\qquad$ $\twoheadrightarrow\sf -1-t = 1$

$\qquad$ $\twoheadrightarrow\sf -t = 1+1$

$\qquad$ $\twoheadrightarrow\sf -t = 2$

$\qquad$ $\pink{\twoheadrightarrow\bf t = -2}$

Henceforth,Value of t will be -2.
