Answer:
see attached
Step-by-step explanation:
Most of this exercise is looking at different ways to identify the slope of the line. The first attachment shows the corresponding "run" (horizontal change) and "rise" (vertical change) between the marked points.
In your diagram, these values (run=1, rise=-3) are filled in 3 places. At the top, the changes are described in words. On the left, they are described as "rise" and "run" with numbers. At the bottom left, these same numbers are described by ∆y and ∆x.
The calculation at the right shows the differences between y (numerator) and x (denominator) coordinates. This is how you compute the slope from the coordinates of two points.
If you draw a line through the two points, you find it intersects the y-axis at y=4. This is the y-intercept that gets filled in at the bottom. (The y-intercept here is 1 left and 3 up from the point (1, 1).)
The answers are 6i/13 and -6i/13. The work it attached below
Answer:
The area of the rectangle <em>TOUR</em> is 80.00 unit².
Step-by-step explanation:
The area of a rectangle is computed using the formula:
Since the dimensions of the rectangle are not provided we can compute the dimensions using the distance formula for two points.
The distance formula using the two point is:
Considering the rectangle <em>TOUR</em> the area formula will be:
Area of Rectangle <em>TOUR</em> = <em>TO × OU</em>
The co-ordinates of the four vertices of a triangle are:
T = (-8, 0), O = (4, 4), U = (6, -2) and R = (-6, -6)
Compute the distance between the vertices <em>T</em> and <em>O</em> as:
Compute the distance between the vertices <em>O </em>and <em>U</em> as:
Compute the area of rectangle TOUR as follows:
Thus, the area of the rectangle <em>TOUR</em> is 80.00 unit².
