Question

Which is the graph of x – y = 1? Image for option 1 Image for option 2 Image for option 3 Image for option 4

Answer 1

That One ..bla bla must be 20 characters long..

Answer 2

Answer:

The graph in the attached figure

Step-by-step explanation:

we have

$x-y=1$

This is a linear equation

Isolate the variable y

$y=x-1$

we know that

The slope of the line is positive $m=1$

The x-intercept is the point $(1,0)$ ----> value of x when the value of y is equal to zero

The y-intercept is the point $(0,-1)$ ----> value of y when the value of x is equal to zero

Plot the intercepts to graph the line

see the attached figure
