HELP PLS In the following diagram, C line intersects line D.

andreev551 [17]

Answer:

A) angles 7 and 8 are vertical angles, making them equal in measure

B) The angle with the measure of (5y-29) and the angle with the measure of (3y+19) are also vertical angles. This means they are equal in measure to each other. You can solve for y by setting these two angles equal to each other.

C) (5y-29)= (3y+19). Add 29 to both sides.

5y = 3y + 48. Subtract 3y from both sides.

2y = 48. Divide both sides by 2.

Y = 24

Plug 24 in for y in the two equations.

(5y-29)

5(24)-29= 91

And

(3y+19)

3(24)+19= 91

Angle 8 and the angle with the measure of (5y-29) are a linear pair. They sum to 180. Remember (5y-29)=91, so

91+ angle 8 = 180. Subtract 91 from both sides.

Angle 8 = 89

If angle 8 is 89, then angle 7 is also 89 because they are vertical angles and equal.

I have to find the slope and the y-intersect from these graphs. It would mean alot if someone could help with at least one of th

Sati [7]

Answer:

Alright bear with me, this is gonna be a long one.

The Y INTERCEPT

So the y-intercept is going to be where the line intersects the Y-AXIS. The y-axis is the vertical part of the graph with the numbers on it.

So, for the first one, the line goes through the origin which means that that the y intercept is going to be (0,0)

The next one, the line intersects the y-axis at (0,1)

Here's a tip: the y-intercept will always have 0 as it's x coordinate.

The Slope

Alright, the slope of a vertical line can be found using an equation. Most typically people will describe the slope as RISE/RUN meaning how many units you move up "rise" and how many units you move horizontally "run" to touch the line. Of course, it's easier when you can identify points.

So to make this a little bit easier to understand, I will show you how to use the equation to find the slope.

$\frac{y2-y1}{x2-x1}$
