From the graphs shown, a horizontal stretch by a factor of b appears to be equivalent to a vertical compression by a factor of a. This implies that a=1b. Are there any values for which this relationship doesn’t work? Write an equation for the relationship between a and b.

For the equations below which statement is true ? -2x=14 6x=-42
