A teacher surveyed her students about the amount of time the students studied for a test and plotted it with their corresponding scores. The data
is shown on the scatterplot below.

A
8.
What does the y-intercept of the best-fit linear model represent?

A student who studied for 48 minutes would expect a score of about
58 on the test.

A student who studied for 0 minutes would expect a score of about 48
on the test.

C. A student who studied for 44 minutes would expect a score of about
52 on the test.

D. A student who studied for 0 minutes would expect a score of about 44
on the test.

Which representation has a constant of variation of -2.5

In δabc shown below, ∠bac is congruent to ∠bca: triangle abc, where angles a and c are congruent given: base ∠bac and ∠acb are congruent. prove: δabc is an isosceles triangle. when completed (fill in the blanks), the following paragraph proves that line segment ab is congruent to line segment bc making δabc an isosceles triangle. (4 points) construct a perpendicular bisector from point b to line segment ac . label the point of intersection between this perpendicular bisector and line segment ac as point d: m∠bda and m∠bdc is 90° by the definition of a perpendicular bisector. ∠bda is congruent to ∠bdc by the definition of congruent angles. line segment ad is congruent to line segment dc by by the definition of a perpendicular bisector. δbad is congruent to δbcd by the line segment ab is congruent to line segment bc because consequently, δabc is isosceles by definition of an isosceles triangle. 1. corresponding parts of congruent triangles are congruent (cpctc) 2. the definition of a perpendicular bisector 1. the definition of a perpendicular bisector 2. the definition of congruent angles 1. the definition of congruent angles 2. the definition of a perpendicular bisector 1. angle-side-angle (asa) postulate 2. corresponding parts of congruent triangles are congruent (cpctc)
