Chapter 2: Section 3 Notes
By the end of the section, you should be able to:
- Students will be able to write AND graph a linear equation in Slope-Intercept Form (y=mx+b).
- Students will be able to write graph a linear equation with zero slope (y=b) and undefined slope (x=#).
- Students will be to identify if a given line has a positive, negative, zero (horizontal), or undefined (vertical) slope.
- Students will be able to find the slope of a line between two points [m= (y2 - y1) / (x2 -x1)].
- Students will be able to identify the x-intercept and y-intercept of a given line.
- Students will be able to recognize the relationship between a linear equation in Slope-Intercept form and a Direct Variation Equation.
Definitions:
- Slope: the ratio of the vertical change to the horizontal change between two points. (rise over run)
- Linear Function: a function whose graph is a line
- Linear Equation: the equation of a linear function. Will be true for any order pair (x,y) that is located on the line.
- Y-intercept: the point where a line crosses the y-axis. Ordered pair will always be (0, #)
- X-intercept: the point where a line crosses the x-axis. Ordered pair will always be (#, 0)
- Slope-Intercept Form: an equation of a line in the form y = mx+b where m is the slope and the point (0, b) is the y-intercept.
