Accepted Answer

Question 7

This table shows values that make an equation true.

Which set of statements describes the equation?

Accepted Answer

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.

Answer

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.

Answer

The slope of the graph of the equation is $$\frac{1}{3}$$ , because x increases by 2 as y increases by 6.

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

The equation is $$y=\frac{1}{3}x+9$$

Answer

The slope of the graph of the equation is $$\frac{1}{3}$$ , because x increases by 2 as y increases by 6.

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

The equation is $$y=9x+\frac{1}{3}.$$
