Answer:
(1) is a function, surjective aka onto,
not bijective aka one to one.
domain is {3,6,12,14,20,22},
range is {4,15,8,11}. More elements in domain means it can't possibly be one to one.
(2) is a relation but not a function, although its inverse is a function. There are fewer elements in the domain than the range, so a function could not be onto but would have to be into or injective.
The relation you get by restricting the domain to {1,19} is a function, injective, so that the image of the domain is a proper subset of the range.

Answer:
see the attached graph
Step-by-step explanation:
When an equation is in <em>standard form</em> (or almost standard form), I like to put it into <em>intercept form</em> for graphing. Here, it is convenient to divide the equation by 2 to put it in standard form (coefficients mutually prime).
x +3y = -3
Now, it is convenient to divide by the constant on the right (-3) to put the equation into intercept form:
x/(-3) +y/(-1) = 1
The denominators are the x- and y-intercepts, respectively. Plot those, (-3, 0) and (0, -1), and draw the line through them.
