Answer:

Yes.

Step-by-step explanation:

Yes.

All non-vertical lines are functions.

Since a line with slope 4 is not a vertical line, this relation is a function.

80% of what number is 64
Thepotemich [5.8K]
Make an equation.

80% = 0.8

'of' is multiplication

'what number' is 'x'

'is' is an equal sign

0.8 * x = 64

0.8x = 64

Divide 0.8 to both sides:

x = 80
