Question

Pls help me on these, i put in the previous problems

Answer 1

ANSWER and EXPLANATION

5. A line only has a slope of 0 if that line is a horizontal line. Hence, we have to identify the horizontal lines on the boat.

The horizontal lines on the boat are:

`EF,\text{ }BC,\text{ }CA,\text{ }and\text{ }BA`

Those are the lines with a slope of 0.

6. A line only has an undefined slope if that line is a vertical line. Hence, we have to identify the vertical lines on the boat.

The vertical lines on the boat are:

`DF,\text{ }FC,\text{ }and\text{ }DC`

Those are the lines with an undefined slope.

7. To find the slope of ED, apply the formula for the slope of a line:

`m=(y_2-y_1)/(x_2-x_1)`

where (x1, y1) and (x2, y2) are two points that lie on the line.

The points (x1, y1) and (x2, y2) are(-11, 4) and (-10, 5). Hence, the slope of the line is:

`\begin{gathered} m=(5-4)/(-10-(-11))=(5-4)/(-10+11) \\ m=(1)/(1) \\ m=1 \end{gathered}`

That is the answer.
