The equation of line is y = 92x - 182631. The slope is 92 and the y-intercept is - 182631. And the health expenditure in 2010 will be 2289.
<h3>What is the equation of a line passing through two points?</h3>Suppose the given points are (x₁, y₁) and (x₂, y₂), then the equation of the straight line joining both two points is given by
In MODE, (second line), fix the number of decimal places to be 2.
Then the slope and the y-intercept values of the Lin Reg line will round to the nearest hundredth.
(x₁, y₁) → (1997, 1093)
(x₂, y₂) → (2002, 1553)
Then we have
y – 1093 = [(1553 – 1093) / (2002 – 1997)] (x – 1997)
y – 1093 = [460 / 5] (x – 1997)
y – 1093 = 92 (x – 1997)
y = 92x – 182631
If x = 2010, then the value of y will be
y = 92 × 2010 – 182631
y = 184920 – 192631
y = 2289

If we say that this linear function is , then the input of the function would be defined by
, which is 2 in this case.
This basically means we are finding when
is 2, or
, or in layman's terms, what the
value is when
is 2.
If we find 2 on the -axis, and see where the line is on the
-axis, we see that when the input of the function is 2, the output is -6.
Hope this helps!
