Answer:

Two straight lines with slopes m and m' are parallel when m = m'

Two straight lines with slopes m and m' are perpendicular when m × m' = - 1.

Step-by-step explanation:

Let us assume that the two non-vertical lines in the slope-intercept form are

y = mx + c ........... (1) and  

y = m'x + c' ............ (2)

If those two lines are parallel then we can say the slope of them will be the same i.e. m = m'

Now, if given two straight lines (1) and (2) are perpendicular to each other and neither of them is parallel to the axes, then we can write m × m' = - 1. (Answer)

<h2>Coordinate Pairs</h2>

Coordinate pairs are organized like (x,y).

  • x tells us the location of the point in relation to the x-axis, the axis that is horizontal.
  • y tells us the location of the point in relation to the y-axis, the axis that is vertical.

To determine a coordinate pair, we can determine each coordinate individually, then put them together.

<h2>Solving the Question</h2>

Notice how the red point sits on the very edge of the graph.

When we look at the x-axis, we can see that it occurs at the number 0 on the x-axis. In other words, the red point occurs when x=0.

When we look at the y-axis, we can see that it lines up with the number 2. In other words, the red point occurs when y=2.

Therefore, when we put the two coordinates together like (x,y), we get (0,2).

<h2>Answer</h2>

(0,2)

Greeley [361]

Answer:

12\dfrac{1}{8}\ feet

Step-by-step explanation:

Sonya drops a marble while standing on a deck 7 \dfrac{7}{8} feet above the ground.

The marble falls 4 \dfrac{1}{4} feet from Sonya's hand to the deck, and then rolls and falls to the ground.

So, the ball falls 4 \dfrac{1}{4} feet from Sonya's hand to the deck  and 7 \dfrac{7}{8} from the deck to the ground, in total

4\dfrac{1}{4}+7\dfrac{7}{8}=4\dfrac{2}{8}+7\dfrac{7}{8}=(4+7)+\dfrac{2+7}{8}=11+\dfrac{9}{8}=11+1\dfrac{1}{8}=12\dfrac{1}{8}\ feet
