Answer:

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.

Explanation:

Given:

The equation is:
y-4=(1)/(3)(x+2)

Express this in the standard form,
y=mx+b

Where,
m is the slope of the line and
b is the y-intercept.


y-4=(1)/(3)((x+2)\\y=(1)/(3)((x+2)+4\\y=(1)/(3)x+(2)/(3)+4\\y=(1)/(3)x+(14)/(3)

So, the slope is
(1)/(3)
and y-intercept is
(14)/(3).

Now, for
x=-2,y=(1)/(3)* -2+(14)/(3)=4

So, first we plot the point
(-2,4).

Since, the slope is
(1)/(3), we have to move 3 units to left and then 1 unit down to plot a second point.

Slope is positive, therefore, we have to move left and then down

Lastly, we have to draw a line passing through these two points to graph the equation
y-4=(1)/(3)(x+2).
