SAT-Math 2020 Spring Week 1:  Linear Models

Welcome new friend Abby!

This is the first class in the Spring Semester. By the end of June, we will go through all the topics including linear/quadratics, number theory foundation (synthetic division, complex numbers, absolute value), geometry (angles, triangles, circles, and volumes), trigonometry, probability, statistics, and reading data.

Lesson Review:

1. Comments & corrections on 2019 Fall Final Term

• When the coefficients of each term are equal, we can say the left and right parts of an equation are equal. (Section 3, Q10, and Section 4, Q16)
• The root square should be non-negative (Section 3, Q15)
• Read every keyword carefully. Know which data you should look into. (Section 4, Q9)
• Pythagorean Triples (3,4,5), (5,12,13), (7,24,25) and so on.
• …

2. Chapter 14: Interpreting Linear Models

• Understanding the meanings/applications of “slope” (rate of change) and ”y-intercept” (the value of the function when x=0).
