This table shows values that make an equation true.

Which set of statements describes the equation?

• The slope of the graph of the equation is 3, because y increases by 6 as x increases by 2.

  The y-intercept of the graph of the equation is 1, because y decreases by 9 when x decreases by 3.

  The equation is y=3x+1.

• The slope of the graph of the equation is 3, because y increases by 6 as x increases by 2.

  The y-intercept of the graph of the equation is 1, because y decreases by 9 when x decreases by 3.

  The equation is y=x+3.
