Basically you just substitute all the x values in.
------------------------------------------------------
x=-5
y=10(-5)+3
y=-50+3
y=-47
If x=-5, then y=-47
------------------------------------------------------
x=-1
y=10(-1)+3
y=-10+3
y=-7
If x=-1, then y=-7
------------------------------------------------------
x=0
y=10(0)+3
y=0+3
y=3
If x=0, then y=3
------------------------------------------------------
x=1
y=10(1)+3
y=10+3
y=13
If x=1, then y=13
------------------------------------------------------
