Work Step by Step

To graph the given linear equation, look for three points that belong to the line. To find three points on the line, assign a value to one variable and then solve for the value of the other variable. When x = 0: $x-y=1 \\0-y=1 \\-y=1 \\y=1(-1) \\y=-1$ The point is $(0, -1)$. When y = 0: $x-y=1 \\x-0=1 \\x=1$ The point is $(1, 0)$. When y = 2: $x-y=1 \\x-2=1 \\x=1+2 \\x=3$ The point is $(3, 2)$. Plot the three points and connect them using a straight line. (refer to the attached image in the answer part above)
