BR UNIT Summary
The Big Race Unit covered three main and VERY important topics:
- Slope of a line
- y-form of an equation (slope and y-intercept form)
- substitution method of solving a system of equations for (x,y)
1) For this unit summary you need to write a description of each main topic.
Slope: describe what the slope of a line means, how to calculate slope, how to draw a slope triangle, what a positive slope looks like, what a negative slope looks like, and the slope of a horizontal line.
y-form of an equation: describe how to write an equation in y-form, describe what each term in the equation means, describe how to find the slope of the line from its y-form equation, describe how to find the y-intercept of the line from its y-form equation, and what it means when a y-form equation does not contain a constant.
Substitution method: describe what a system of equations is, describe what form the answer to the solution of a system of equations is, describe the TWO methods of substitution.
2) For each topic you need to choose two problems to solve and demonstrate your understanding of the topic. For the substitution method you need to choose and solve a total of four problems, two for each method.
Your work must be shown in detail, step-by-step. Graphs must be drawn with rulers and the axes and lines must be labeled.
This Unit Summary is worth 100 points and is due Friday February 18th.
