Which of the following regressions represents the strongest linear relationship between x and
y?
Regression 1
y = 0.3 + b
a = 17.5
Regression 2
y = ax + b
a = -8.7
b = 1.9
b = -14
r = 0.2251
r= -1.1322
Regression 3
y = 0.2 +6
a = -18.4
Regression 4
y = ax + 5
15.3
a =
b = 15.3
b= -7.1
r= -0.3818
r=0.6337

109 is the nearest whole number/final answer! : )

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.
