Question
Using the linear model, y = 10 x + 10 predict the temperature in Hayward in July ( x = 7).
- 70
- 10
- 80
- 85
Hint:
Substitute the value of x in the linear model equation.
The correct answer is: 80
The linear model, y = 10 x + 10
The temperature in Hayward in July ( x = 7). Substituting the value of x in above equation:
y = 10(7) + 10
Thus, y = 80 is the temperature of Hayward in July.
