See below !

Explanation:

It's linear as you see the power of x first degree

GET

x-intercept when y=0

x=-3

(-3,0)

y-intercept when x=0

y=1

(0,1)

SO,

Take the two point and draw a straight line.

Please read the explanation.

Explanation:

" "
Given:

Linear equation color(red)(y = x/3 + 1

Steps:

(1) Graph the Parent Function: color(blue)(y=x

(2) Graph the function color(green)(y=x/3

(3) Graph the given function color(red)(y=x/3 + 1

(4) Reflection

color(black)("Step 1"

Graph the Parent Function: color(blue)(y=x

enter image source here

Observe that the linear equation goes through the origin (0,0)

color(black)("Step 2"

Graph the function color(green)(y=x/3

enter image source here

Observe that the linear equation goes through the origin (0,0) as well similar to the parent function.

color(black)("Step 3"

Graph the given function color(red)(y=x/3 + 1

enter image source here

Observe the following:

(a) x-intercept is at (-3,0)

(b) y-intercept is at (0,1)

color(black)("Step 4"

We will view all the graphs together and reflect on the behavior of the given function color(red)(y = x/3 + 1.

enter image source here

Reflection:

(a) Graph of the function color(green)(y=x/3 and the graph the given function color(red)(y=x/3 + 1 form parallel lines.

(b) Graph of the given function color(red)(y=x/3 + 1 is a vertical shift of "1 unit" on the y-axis from the origin: (0,0).

Hope you find this solution helpful.
