✒️VARIATIONS

» For numbers 6-7, find the constant of variation:

• 6) y varies directly as x, and y=48 when x=4
• 7) y varies inversely as x, and y=3 when x=15

#6: y varies directly as x, and y is 48 when x is 4

» Create an equation of a direct variation in which k is the constant of the variation.

» Find the constant.

The constant of the variation is 12

#7: y varies inversely as x, and y is 3 when x is 15

» Create an equation of an inverse variation in which k is the constant of the variation.

» Find the constant.

The constant of the variation is 45
