Use the given data to find the equation of the regression line. Round the final values to three significant digits, if necessary. x 0 3 4 5 12
y 8 2 6 9 12

a. y^=4.98+0.425x
b. y^=4.98+0.725x
c. y^=4.88+0.625x
d. y^=4.88+0.525x

a

step-by-step explanation:

- (2, -7)

- lines r and s and lines t and u must be parallel

isocolese triangle

we know that the line connect a and b is the hyptonuse

so first find the hypotonuse length using the distance formula, call the length c

since it is an isocolese triangle, the lengths of the legs are the same

using pythagorean theorem,

in this case, a=b since isocolese triangle so we get

or

we can find c so we can find the distances

we know that if we draw 2 circles, each has center at a and b, and find where they intersect, we can the 2 possible locations for c

if a has center at (xa,ya) and b has center at (xb,yb), then we can solve where

and

intersect to find where they intersect

i'm not going to put an example because i have to go to class. i hope this explanation is enough
