Question 1059655: I am working on Graphing with plots and slopes I am having trouble with this question for homework it says graph the equation by determining the missing values needed to plot the ordered pairs. y-x=1;(3,),(,8),(4,) not sure what is the slope or plot for this graph.

EQUATION: y-x=1.

TABLE OF x,y VALUES

x       |       y
-----------------------
3       |         
        |      8
4       |

Calculate the missing values. You have the equation to do this.

y-x=1
-
y-x%2Bx=1%2Bx
y%2B0=1%2Bx
y=x%2B1
-
y-x-y=1-y
y-y-x=1-y
-x=1-y
-1%28-x%29=-1%281-y%29
x=y-1

y - x = 1 =====> y = x + 1

y = 3 + 1 ------ Substituting 3 for x

y = 4



Do the same for the others, by substituting given values, and solve to find the other

You should get coordinate points: 

Plot the points and then JOIN them. That's your graph. 

Very simple......nothing COMPLEX!
