Inside the Classroom

Week of 12/16 - 12/20

This week we are beginning our unit on inequalities. When solving one variable inequalities please keep in mind:

We solve linear inequalities using a similar process to solving linear equations.
When multiplying or dividing by a negative number, we switch the inequality sign.
All one variable inequalities can be graphed on a number line by following the direction of the inequality sign.

These weeks we are learning about the different techniques we can use to solve Systems of Equations. Some important facts to remember are:

Substitution is best used when we are provided the value of one of the variables: "x =" or "y =".
Elimination is best used when the coefficients of matching variables are the same or opposite numbers.
Graphing is best used when both equations are provided in slope intercept form.

This week we are learning about the different forms to represent the equation of a line. Some important facts to remember are:

When the equation of a line is in slope-intercept form we are able to identify the slope and the y - intercept.
When the equation of a line is in point-slope form, we are able to identify the slope and a point on the line.
Parallel lines have the same slope but the slopes of a perpendicular lines are negative reciprocals of each other.

This week we are learning about scientific notation. Some important facts to remember are:

For a number to be in scientific notation, it must be between 1 and 10 and multiplied by a power of 10.
When moving the decimal to the left, the exponent will increase.
When moving the decimal point to the right, the exponent will decrease.
