Answer:

Simplifying x + 6.7 = -9.7 Reorder the terms:

6.7 + x = -9.7 Solving 6.7 + x = -9.7 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-6.7' to each side of the equation.

6.7 + -6.7 + x = -9.7 + -6.7 Combine like terms: 6.7 + -6.7 = 0.0

0.0 + x = -9.7 + -6.7

x = -9.7 + -6.7 Combine like terms: -9.7 + -6.7 = -16.4

x = -16.4 Simplifying x = -16.4

Take west to be the positive direction. The height of a sloped roof above the place where you stand is 12

<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,

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