The table shows the test score and the number of minutes of daily practice. determine the correct statements related
to the line of best fit. select all that apply.
minutes of practice 10 15 20 25 30 35 40 45 50
test score 65 65 70 80 75 80 85 90 95
the line of best fit must start at the origin
the line of best fit will intersect the positive 3-axis
the line of best fit will intersect the negative z-axis.
the line of best fit will intersect the positive y-axis.
the line of best fit will intersect the negative y-axis.

part a: triangles gcb and epb

part b. sides cg and rp are parallel by definition of parallelogram.

angles cgb and e are congruent by being alternate interior angles of parallel lines cut by a transversal. angles gbc and ebp are congruent because they are vertical angles. by aa similarity, the triangles are similar.

part c. since the triangles are similar, the ratios of the lengths of corresponding sides are equal.

calculation of be:

gb/be = cb/bp

(400 ft)/be = 300/200

(400 ft)/be = 3/2

3be = 2 * 400 ft

3be = 800 ft

be = 800/3 ft

calculation of pe:

gc/pe = cb/bp

(350 ft)/pe = 300/200

(350 ft)/pe = 3/2

3pe = 2 * 350 ft

3pe = 700 ft

pe = 700/3 ft

y = -1

x = 8

hope this !
