Square, rhombus and rectangle are also parallelograms.
A line through two points A, B can be found by the point-slope form of the formula:
(y-ya)=m(x-xa)............(1)
and
m=(yb-ya)/(xb-xa).......(2)
where A(xa,ya), B(xb,yb) and m is the slope between points A & B.
Substituting
A(xa,ya)=A(1,3)
B(xb,yb)=B(0,2)
From (2)
m=(yb-ya)/(xb-xa)
=(2-3)/(0-1)
=-1/(-1)
=1
Substitute in (1) : (y-ya)=m(x-xa)
y-3=1(x-1)
Distribute and simplify
y=x-1+3=x+2
or
y=x+2 .................(3a) equation required in slope-intercept form
x-y+2=0...............(3b) equation in standard form
Answer:
Step-by-step explanation:
slope=(-1-0)/(6-3)=-1/3
reqd. eq. of line is
y-0=-1/3(x-3)
3y=-x+3
x+3y=3
Answer:C) Children cannot use counters for the initial amount.
Step-by-step explanation:Problem solving allows students to use mathematical concepts, skills and the relationships among them to solve problem situations with different levels of difficulties. Problem solving framework allows students to solve mathematical situations by assisting them to handle or approach problem solving systemically.
There are basically four structures they are
(1) Join
(2) Separate
(3) Part-Part-Whole
(4) Compare.
JOIN AND SEPARATE STRUCTURES INCLUDE ACTIONS THAT INCREASE OR DECREASE A QUANTITY.
The part-part whole does not involve an action but it has a relationship between a particular whole and its two separate parts.
The compare structure also does not involve an action,but it compares two unconnected and distinct sets.
