Direct Variation, Direct Variation
y = 2x
If x = -7 when y = -14, write the direct variation equation.
y = 0.5x
If y = -7 when x = -14, write the direct variation equation and find y when x = 20.
y = 10/9x
If y = 10 when x = 9, write the direct variation equation.
y = 4.5x
If y = 27 when x = 6, write the direct variation equation.
y = 4x
If y = 8 when x = 2, write the direct variation equation and find y when x = 5.
