a student creates a table of the equation y = 5x + 8. the student begins the table as shown below.
column a : 1
column b : 5(1)+8
column c : 13
which shows the correct headings for the columns?
column a = x, column b = 5x + 8, column c = y
column a = y, column b = 5x + 8, column c = x
column a = x, column b = y, column c = 5x + 8
column a = y, column b = x, column c = 5x + 8
