Answer:

Step-by-step explanation:
The points on the straight line are (P, 0) and (0, R).
The slope would be

And
, because the y-intercept is at (0, R).
So, the equation of this line would be

Where we multiply the equation by 

Therefore, the equation that represents this line is

<h2>
So, the right answer is B.</h2>
Answer:
type 2 in the first box,
13/4 in the second box, and
-9/8 in the third one
Step-by-step explanation:Notice that you are asked to write the following quadratic expression in vertex form, so you need to find the "x" value of the vertex, and then the "y" value of the vertex:

Which in our case is: -13/4
and the value of the y for the vertex is obtained using the functional expression when x equals -13/4:

Then your expression for this quadratic should be:

Then type 2 in the first box, 13/4 in the second box, and -9/8 in the third one
To form a linear pair means that when added, they equal 180 degrees.
but if they have equal measures....180/2 = 90...then they would both equal 90 degrees.....and 90 degrees is a right angle.
So ABC and CBD are both right angles
