Here's a plot showing the interest rate on a 3-month bond from 1950 to 1980, and a regression model fit to the relationship between the Rate (in %) and Years since 1950. Complete parts a through d. 0 15 30 0 6 12 Years since 1950 Rate (%) A scatterplot with horizontal axis labeled "Years Since 1950" from 0 to 30 plus in intervals of 15 and vertical axis labeled "Rate (Percent)" from 0 to 12 in intervals of 6 contains ten points tightly clustered around the line rising from left to right and passing through the points (0, 0) and (25, 7). The two rightmost points are farther from the line than any of the others, at (26, 5) and (30, 11). All coordinates are approximate. Dependent variable is: Rate R-squaredequals=79.479.4% sequals=1.3441.344 VariableVariable Coefficient Intercept 0.2803450.280345 Year-1950 0.2690420.269042 a) What is the correlation between rate and year? nothing

It must have the same slope as the given line, so

m = -A/B = -1/-2 = 1/2

So far, we have

y = mx + b = x/2 + b

Use the given point to find b.

4 = -2/2 + b = -1 + b

b = 5

y = x/2 + 5

Multiply through by 2.

2y = x + 10

Standard form:

x - 2y = -10
