This news segment mentions visibility and kids wanting to see themselves in the media the
kumpel [21]
The question was split so i tried to understand it the best i could but i would say:

This news segments connects to our topic of diversity mainly because every kid doesn’t want to be in the media. And that’s why it’s diverse. Typical children like to play or run around for fun, but certain children have their motives and they find what they to do at an early age. Diversity is full of different passions and children are fully capable of having a passion at a young age.

On a coordinate plane, line M N goes through (negative 4, 0) and (4, 2). Point P is at (2, negative 4). Which point on the x-axi
LekaFEV [45]

Answer:

C, (1,0)

Explanation:

A perpendicular line is when 2 lines cross each other with right angles, which are 90⁰ angles. Two lines are only perpendicular when the lines slopes are negative reciprocals to each other.

To find the slope of the first graph use, (y2-y1)/(x2-x1)

This is, 2-0/4+4

2/8

1/4 is the slope for the first line.

The negative reciprocal of this is -4.

We are also looking for a point on the x axis, so this eliminates answer choice A, and B, because they aren't even on the x axis.

When you test out answer choice c it will show that,

-4-0/2-1=-4/1 which is just -4.

These points on line p will pass each other when you add +4, y=-4x+4. So because of both of these lines negative reciprocating slopes, it shows that it will be answer C.
