Question

Which steps should be used to graph the equation y – 4 = (x + 2)? 1. Plot the point (2, 4). 2. From that point, count left 3 units and down 1 unit and plot a second point. 3. Draw a line through the two points. 1. Plot the point (2, 4). 2. From that point, count left 1 unit and down 3 units and plot a second point. 3. Draw a line through the two points. 1. Plot the point (–2,4). 2. From that point, count left 3 units and down 1 unit and plot a second point. 3. Draw a line through the two points. 1. Plot the point (–2,4). 2. From that point, count left 1 unit and down 3 units and plot a second point. 3. Draw a line through the two points.

Answer 1

Answer with explanation:

We have to graph the Linear equation:

→ y-4 =x+2

⇒To draw a line you need two points that lies on the line.

→Point (-2,4) lies on the line,as

L HS→4-4=0

R HS → -2 +2=0

→From Point (-2,4) finding a point which is left 1 unit and down 3 units  is equal to = (-2-1 ,4-3)

 = (-3,1)

→And from  Point (-2,4) finding a point which is left 3 unit and down 1 unit  is equal to = (-2-3 ,4-1)

 = (-5,3)

→None of the two points that is (-3,1) and (-5,3) lie on the linear function

which is, y-4 =x+2.

≡None of the option

 

Answer 2

Answer:

Option 3

Step-by-step explanation:

1. Plot the point (–2,4). 2. From that point, count left 3 units and down 1 unit and plot a second point.

The slope is 1/3, the 1 being the change in y (thats why you count down 1 unit) and the 3 being the change in x (thats why you count left 3 units).

Point-slope form: y-y₁ = m (x-x₁)

So, y1 is 4 and x1 is -2. This is why you plot the point (-2, 4). In the equation, the sign for -2 is flipped because x - (-2) is the same thing as x + 2.
