when dealing with graphing linear equations such as y= -1+x

Question

i have a question such as y=-1+x how do you solve this question and how do you graph it

Answer 1

make a table of x's and y's and graph on the coordinate plane, the x-axis and y-axis

y=-1+x

pick values for x and determine the corresponding y values

x=0,   y=-1,   (0,-1)

x=1,   y=0,    (1,0)

x=2,   y=1,    (2,1)

x=-2,  y=-3,   (-2,-3)

x=3,   y=2,     (3,2)

x=-3,  y=-4,   (-3,-4)

you can pick as many ordered pairs as you like, however, two points determine a line and choose a third point to make sure there are no mistakes

 

the line should look something like this:

                                                               .

                                                             .
