As we know, that all squares are quadrilateral but its converse is not necessarily true.
Set of Quadrilaterals is a super set of set of squares.
i.e. set of squares ≤ set of quadrilaterals.
From the picture, we can know that quadrilaterals consists of all the squares and square is a type of quadrilateral. All the squares belong to quadrilaterals, while not all the quadrilaterals belong to squares.
[It's important to have a good understanding of venn diagram as it illustrates the connection between things in it]
We can use the points in either order and you will still get the same slope. I usually solve in order that is given. So the first coordinates I label (x1,y1) and the second is (x2,y2).
Slope=m=(y2-y1)/(x2-x1)
m=(9-5)/(3-1)=4/2=2
Slope is 2.

So the second train is going 1/5 the speed of the first train, and sooo it’ll probably take 3.25 or 3.5 hours I think
Answer:
(x, y) = ( -4 , 4)
Step-by-step explanation:
STep 1: substitute the given value of x into the equation -7 x - 6y = 4 which will be -7 (-3 y + 8) - 6 y = 4
STEP 2: solve the equation for y so basically -7 (-3 y + 8) - 6 y will be y = 4
STEP 3:substitute the given value of x into the equation so y = 4 would be
x = -3 x 4 + 8
STEP 4: solve the equation for x. -3 x 4 + 8 which you'd end up with x = -4
