What formula is this: m = y 2 − y 1 x 2 − x 1 m\ =\ \frac{y_{2\ }-\ y_1}{x_2\ -\ x_1}_{ } m = x 2 − x 1 y 2 − y 1

slope equation (Proportional Relationship)

slope-intercept equation (Nonproportional Relationship)

What formula is this: y = m x + b y\ =\ mx\ +b y = m x + b

slope-intercept equation (Nonproportional Relationship)

slope form equation (Proportional Relationship)

Which of the following equations represents the line that is graphed on the coordinate grid below?

y = − 1 3 x + 2 y\ =\ -\frac{1}{3}x\ +\ 2 y = − 3 1 x + 2

y = − 3 x − 6 y\ =\ -3x\ -6 y = − 3 x − 6

y = − 3 x + 2 y\ =\ -3x\ +2 y = − 3 x + 2

y = − 1 3 x − 6 y\ =\ -\frac{1}{3}x\ -\ 6 y = − 3 1 x − 6

What is the equation for this graphed line?

y = 2 x − 1 y\ =\ 2x\ -\ 1 y = 2 x − 1

y = 2 x + 1 y\ =\ 2x\ +\ 1 y = 2 x + 1

y = − 2 x − 1 y\ =\ -2x\ -1 y = − 2 x − 1

These two lines are graphs of nonproportional relationships. What makes them nonproportional?

They do not go through the origin.

They do not show a constant ratio.

Which equation shows a proportional relationship?

y = 2 x y\ =\ \frac{2}{x} y = x 2

y = 2 x − 2 y\ =\ 2x\ -\ 2 y = 2 x − 2

y = 1 2 x + 1 2 y\ =\ \frac{1}{2}x\ +\ \frac{1}{2} y = 2 1 x + 2 1

Is this mapping diagram a function? Why?

No, because the x-value 11 has two y-values pair with it.

Yes, because the x-value 11 has two y-values pair with it.

Yes, because each x-value has only one y-value paired with it.

No, because each x-value has only one y-value paired with it.
