Question

Can somebody help me with this linear worksheet?

Answer 1

the x column tells you the value of x
the next column tells you it substituted the x value into the equation
and the y column is the y value after substituting x into the equation
in the column (x,y)
you are writing a coordinate using the x value and y value

so for question 3
i will show you one example

x=-2

substitute x=-2 into
y=3x-1
so you replace x to be -2

y=3(-2)-1
y=-6-1
y=-7

in the last column (x,y)
you will get
(-2,-7)


to draw the graph, you will plot the coordinates onto the graph

so if you have
(1,1)
(2,2)
(3,3)

you put an x on the part of the graph where x=1 and y=1
an x where x=2 y=2
an x where x=3 y=3

then draw a straight line going through every point

this is the same for all of your questions

Answer 2

have fun
