Question

Graph the function.

y=x+4

Answer 1

The graph in the attached figure

Explanation:

we have

`y=x+4`

This is a linear equation

The graph is a straight line

To graph a line we need two points

Find the intercepts of the graph

Find the y-intercept (value of y when the value of x is equal to zero)

For x=0

`y=0+4\\y=4`

so

The y-intercept is the point (0,4)

Find the x-intercept (value of x when the value of y is equal to zero)

For y=0

`0=x+4\\x=-4`

so

The x-intercept is the point (-4,0)

Plot the intercepts, connect them and graph the line
