Given:
The descriptions and equations. The equations are
[tex]y=4x[/tex]
[tex]y=x+4[/tex]
To find:
The correct description for each equation and match them.
Solution:
We know that, "+" is used for more and "×" is used for times.
Additive: y is 4 more than x.
[tex]y=x+4[/tex]
Additive: x is 4 more than y.
[tex]x=y+4[/tex]
Multiplicative: y is 4 times x.
[tex]y=4x[/tex]
Multiplicative: x is 4 times y
[tex]x=4y[/tex]
Therefore, the correct description for the equation [tex]y=4x[/tex] is "Multiplicative: y is 4 times x " and the correct description for the equation [tex]y=x+4[/tex] is "Additive: y is 4 more than x. "
