OlgaM077 [116]

Answer:

=17

Step-by-step explanation:

We need the slope and the y-intercept to find the equation of the linear model.

This line goes through (0,28) and (1,26), so the slope is

\frac{26 - 28}{1} = -2

1

26−28

=−2

The equation that best describes this model is

\widehat{y} = -2x + 28

y

=−2x+28

Plug in x = 5.5 in the above equation to get

\widehat{y}

y

=−2x+28

=(−2)(5.5)+28

=−11+28

=17

Based on this equation, the date in April her flowers will bloom if the average temperature in March is
