Three vertices of a rectangle are given. Find the coordinates of the fourth vertex.
Nonamiya [84]
So we can get pairs
(x,y)
we have
(-3,-3)
(7,-3)
(7,2)


so list known ones
x=-3,7,7
y=-3,-3,2
we find pairs
x=7 and 7
y=-3 and -3
the missing one is another -3 for x and 2 for y
therefor the last point is
(-3,2)

Greg is trying to solve a puzzle where he has to figure out two numbers, x and y. Three less than two-third of x is greater than
-Dominant- [34]
The first inequality is
(2/3)x - 3 ≥ y
or 
y ≤ (2/3)x - 3           (1)

The second inequality is
y + (2/3)x < 4
or
y < 4 - (2/3)x           (2)

A graph of the two inequalities indicates the solution as a shaded region in the figure below.

Find the slope of the line that passes through the points (1,-4) and (3,-1).
Delvig [45]

Answer:

The answer is

\frac{3}{2}  \\

Step-by-step explanation:

The slope of a line given two points can be found by using the formula

m =  \frac{ y_2 - y _ 1}{x_ 2 - x_ 1}  \\

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(1,-4) and (3,-1)

The slope is

m =  \frac{ - 1  -  - 4}{3 - 1}  =  \frac{ - 1 + 4}{2}  =  \frac{3}{2}  \\

We have the final answer as

\frac{3}{2}  \\

Hope this helps you
