Answer:
7
4
Step-by-step explanation:
The <u>actual values</u> are shown on the given graph as <u>blue points</u>.
The <u>line of regression</u> is shown on the given graph as the <u>red line</u>.
From inspection of the graph, in the year 2000 the actual rainfall was 43 cm, shown by point (2000, 43). It appears that the regression line is at y = 50 when x is the year 2000.
⇒ Difference = 50 - 43 = 7 cm
<u>In 2000, the actual rainfall was </u><u>7</u><u> centimeters below what the model predicts</u>.
From inspection of the graph, in the year 2003 the actual rainfall was 44 cm, shown by point (2003, 40). It appears that the regression line is at y = 40 when x is the year 2003.
⇒ Difference = 44 - 40 = 4 cm
<u>In 2003, the actual rainfall was </u><u>4</u><u> centimeters above what the model predicts.</u>
Answer:
Look at the whole numbers and not the tenths hundreds and stuff. 1,2,3.25 and then fraction.

Step-by-step explanation:
Answer:
yes
Step-by-step explanation:
Given the 2 equations
y = 
x + 6 → (1)
y = - x + 5 → (2)
Substitute y = x + 6 into (2)
x + 6 = - x + 5 ( add to both sides )
x + 6 = 5 ( subtract 6 from both sides )
x = - 1 ( divide both sides by )
x = 
= - 
← one solution
