<u>Given:</u>

Take west to be the positive direction. The height of a sloped roof above the place where you stand is 12  feet. If you move 3 feet west, the height is 10 feet.

We need to determine the slope.

Let x denote the standing place.

Let y denote the height.

Writing the given as coordinates, we get;

(0,12) and (3,10)

<u>Slope</u>:

The slope can be determined using the formula,

m=\frac{y_2-y_1}{x_2-x_1}

Substituting the coordinates (0,12) and (3,10), we have;

m=\frac{10-12}{3-0}

m=\frac{-2}{3}

Thus, the slope is m=-\frac{2}{3}

Mice21 [21]

Answer:

y - 1 = 3 ( x - 2)

Step-by-step explanation:

The formula for point slope form is y-y1=m(x-x1)

Just substitute the given information into the equation to get your answer.

(reminder m=slope, y1=the given y value, x1= the given x value)
