Work Step by Step
To graph the given linear equation using the slope and y-intercept, perform the following steps: (1) Solve for the x and y intercepts. To find the x-intercept, set $y = 0$, and then solve for $x$: $x+y=4 x+0= 4 \\x=4$ This means that the x-intercept is at $(4, 0)$. To find the y-intercept, set $x = 0$, and then solve for $y$: $x+y = 4 \\0+y=4 \\y=4$ This means that the y-intercept is at $(0, 4)$. (2) Plot the intercepts, and then connect them using a line.
