Question

What is the slope of the line that passes through the points (5,−4) and (7, -4) ?Write your answer in simplest form.

Answer 1

Undefined

Explanation:

`\boxed{slope = (y1 - y2)/(x1 - x2) }`

☆ (x₁, y₁) is the first coordinate and (x₂, y₂) is the second coordinate.

Slope of the line

Thus, the slope of the line is undefined.

(Since 2 cannot be divided by zero)

Notice that the two coordinates have the same y- coordinate of -4. This means that the line is a vertical line. Vertical lines have undefined slopes.
