we have
y= 2x+7
this is the equation of the line
Make the table
For different values of x, calculate the values of y
so
For x=-1
y=2*(-1)+7
y=5
For x=0
y=2*(0)+7
y=7
For x=1
y=2*(1)+7
y=9
For x=2
y=2*(2)+7
y=11
therefore
we have the points
(-1,5) (0,7) (1,9) (2,11)
Plot the points and join them to graph the line
using a graphing tool
see the attached figure
