Mid - Chapter Test
Do the study guide to help prepare you for the chapter test. Make sure you click on the star to check your answers as you go.
Make sure you have memorize
- Slope intercept form: y = mx + b
- Point-slope form: y - y1 = m(x - x1)
- Standard form: Ax + By = C
- Slope formula: m = (y2 - y1)/(x2 - x1)

-
Make a scatter plot (on Desmos, but understand how to do it by hand if you needed to)
-
Make a line of best fit for the scatter plot (on Desmos)
-
Write and equation for the line of best fit (from the Desmos calculation)
4.5

4.6
Regression Lines - Graphing Calculators
Students will be able to...
-
know how to use a TI-84 Graphing Calculator
-
Other graphing calculators can be used in class, however they will not be taught.
-
-
Make sure you know the buttons to press to
-
reset the calculator
-
turn on diagnostics
-
input data into a table
-
find correlation coefficient (r)
-
make a regression line
-
-
Understand what the number for the correlation coefficient means
IXL Practice
-
There are not any good practices for Algebra 1 on IXL on this topic since we are just introducing it. You can try this Algebra 2 one, but it might include things you haven't learned yet.
Students will be able to...
-
Given a table of points, be able to write the inverse points
-
Given a line on a graph, be able to graph the inverse line
-
Given an equation/function, be able to write the inverse equation/function
-
Note that y= and f(x)= is the same thing. The "y" means it's an equation, the "f(x)" means it's in function notation.

CHAPTER 4
This activity helps you organize all the ways you can write equations in slope intercept form. You are given different information to start with in each question so you will have a different, yet similar, process for each one. All answers should be written in slope-intercept form.
This should take about 15 minutes.
