Question

Which graph represents y – 1 = 2(x – 2)? Thank You! :)

Answer 1

Answer:

Option A    

Step-by-step explanation:

Given : Equation $y-1 = 2(x -2)$

To find : Which graph represents the given equation

Solution :

First thing we plot the graph of the equation.

We see that graph cuts at point (1.5,0) and (0,-3) to the coordinates.

From the given graph Option A graph cuts to these points.

Therefore, Option A is correct.

Refer the attached graph A.

Answer 2

Y = 2(x – 2)+1
y = 2x – 4+1
y = 2x-3

insert x=0 -> y=-3, only the first graph passes through (0,-3) -> it is the first graph
