Which graph represents y – 1 = 2(x – 2)?

The graph is attached below

Step-by-step explanation:

y – 1 = 2(x – 2)

y-1 = 2x - 4

add 1 on both sides

y = 2x - 3

To graph the given equation we make a table

Plug in some number for x and find out the value of y

x      y = 2x-3

-1       2(-1)-3= -5

0        2(0) -3= -3

1          2(1) -2= -1

The point to get the graph of the given equation is

(-1,-5)   (0,-3) (1,-1)

The graph is attached below

The answer is the first graph or graph A.

BTW this is just the short answer...

Its quicker.      :-)

3x^3-x^2+6x-9

solution:

we have to construct

∠m nt ≅ ∠p qr

the steps to draw this construction are

step 1: use a compass to draw an arc from point q which intersects the side pq at point a and the side qr at point b.

step 2: draw a segment nt and use the same width of the compass to draw an arc from point n which intersects the segment nt at a point x.

step 3:

step 4: join points n and y using a straightedge.

step 3:

option (d).maintaining the same width of the compass as ab, draw an arc from point x such that it intersects the arc drawn from n in a point y.

to draw   congruent angles , 1. width of compasses while drawing two angles should be same i.e from point at which angle has to be drawn, 2.the distance between the two points where the compass intersects the two sides should be same while drawing any two congruent angles.
