Answer:

-2

Step-by-step explanation:

$y = kx + n$

When you insert the given points you get

$3k + n = 4 \\$

$7k + n = - 4 \\$

Than you multiply the first one by - 1 and sum it with the second to get rid of n

$4k = - 8 \\ k = - 2$

What quadrilateral always has 4 congruent angles and opposite that are congruent and paralle

nignag [31]

Another quadrilateral that you might see is called a rhombus. All four sides of a rhombus are congruent. Its properties include that each pair of opposite sides is parallel, also making it a parallelogram. In summary, all squares are rectangles, but not all rectangles are squares.

What is the solution to 1/3(s-2)=s+4

raketka [301]

$\frac{1}{3} * (s-2)=s+4 \\ \\ \frac{s-2}{3}=s+4 \\ \\ s-2=3(s+4) \\ \\ s-2= 3s+12 \\ \\ s-3s=12+2 \\ \\ -2s= 14 \\ \\ \boxed{s= -\frac{14}{2}=-7}}$
