Sagot :

we have the function

f(x)=x-4

That is the equation of a line

to graph a line we need at least two points

so

Find out the intercepts

step 1

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

For x=0

f(x)=0-4

f(x)=-4

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

step 2

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

For y=0

0=x-4

x=4

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

step 3

Plot the points (0,-4) and (4,0), join them, to graph the line

see the attached figure to better understand the problem
