This equation shows the linear relationship between the number of minutes since Micah started heating a pot of water and the temperature of the water. x represents the number of minutes, and y represents the temperature in degrees Celsius.

Question

Now, solve for y, the temperature of the water after 6 minutes.
y
=
10x+20
y
=
10·6+20
y
=

Answer 1

To find the temperature of the water after 6 minutes, substitute \( x = 6 \) into the equation \( y = 10x + 20 \):

\[ y = 10 \cdot 6 + 20 \]

Calculating this gives:

\[ y = 60 + 20 \]

\[ y = 80 \]

So, the temperature of the water after 6 minutes is \( y = 80 \) degrees Celsius.
