What's the slop of the line whose equation is 87 = 7 - 2y?

This is similar to the other one where i posted. You subtract 7 from both sides so the equation will be 80= -2y. Then divide both sides by -2, and the equation will be y=-40. This is a straight line so the slope is zero. If there are no x's in your equation, the slope will always be zero.

To find the slope of a line, we typically look at the equation in the form y = mx + b, where m represents the slope. However, in the given equation, 87 = 7 - 2y, we don't have it in that form.

To determine the slope, we need to rearrange the equation to isolate y on one side. Let's go through the steps:

1. Start with the equation 87 = 7 - 2y.

2. Subtract 7 from both sides to move the constant term to the right side: 87 - 7 = -2y.

3. Simplify 87 - 7 to get 80: 80 = -2y.

4. Divide both sides of the equation by -2 to solve for y: 80 / -2 = y.

Calculating 80 / -2, we find that y = -40.

Since this equation only involves y and not x, it represents a horizontal line parallel to the x-axis. In such cases, the slope is always zero.
