y+=+3x+%2B+2:this is equation of a line (linear function, a graph is a line)
here you have one point (or ordered pair, x and y coordinates) that lie on a given line:
(x,y )=(1,y ); so, you are given x coordinate and you need to find y coordinate, and you can find it using given equation
y+=+3x+%2B+2...plug in 1 for x
y+=+3%2A1+%2B+2...solve for y
y+=+3%2B+2
y+=+5
so, your point is (1,5 ) and your answer is
c. 5

here is a graph:
