SHSAT: Grade 9 extension practice

A method you can use

1. Add standards through grade 8 to the common grade-8 foundation. The official grade-9 mini forms supplement the full practice forms.
2. For a linear model, distinguish the fixed amount from the rate. Two observations can determine both; proportional reasoning alone fails when the intercept is nonzero.
3. For systems, a proposed ordered pair must satisfy both equations. For transformations, follow the specified order because a reflection and translation generally do not commute.
4. For Pythagorean or irrational-number work, compare exact squares before estimating roots. This grade tag is a preparation filter, not an official score scale or separate calibrated form.

Before you answer

Read the directions first. Check whether the question wants one answer or several, and what your answer has to include.
