Answer 1

1. Slope-intercept form: The slope-intercept form of a linear equation is expressed as \(y = mx + b\), where \(m\) represents the slope and \(b\) represents the y-intercept.

2. Point-Slope form: The point-slope form of a linear equation is given by \(y - y_1 = m(x - x_1)\), where \(m\) is the slope and \((x_1, y_1)\) is a specific point on the line.

3. Standard form: The standard form of a linear equation is \(Ax + By = C\), where \(A\), \(B\), and \(C\) are integers and \(A\) is non-negative.

4. Slope: The slope of a line measures its steepness and is calculated as the ratio of the vertical change (rise) to the horizontal change (run) between two points on the line.

5. X-intercept for a graph: The x-intercept of a graph is the point where the graph crosses the x-axis, indicating that the value of \(y\) is zero.

6. Y-intercept for a graph: The y-intercept of a graph is the point where the graph crosses the y-axis, indicating that the value of \(x\) is zero.

7. Y-intercept when the graph is proportional: In a proportional graph, the y-intercept is always zero, indicating that the relationship passes through the origin.

8. Slope formula and meaning: The slope formula is given by \(\text{slope} = \frac{y_2 - y_1}{x_2 - x_1}\), and it quantifies how much \(y\) changes for a given change in \(x\).

9. Similar triangles as it relates to slope: Similar triangles show that the ratio of the corresponding sides remains constant, which reflects the concept of slope being a constant ratio of rise to run.

10. 2 ways to express a linear proportional equation: A linear proportional equation can be expressed in the form \(y = kx\) or as \(y/x = k\), where \(k\) is the constant of proportionality.

11. “k” and “m” stand for what in each equation?: In the equation \(y = kx\), \(k\) represents the constant of proportionality, while in the slope-intercept form \(y = mx + b\), \(m\) represents the slope of the line.

12. Rate of change: The rate of change represents how a quantity changes with respect to another quantity, often expressed as a slope in linear relationships.

13. Constant Rate of Change - Linear: A constant rate of change in a linear function indicates that the change in the dependent variable is consistent for equal changes in the independent variable.

14. Proportional relationship: A proportional relationship is one where two quantities maintain a constant ratio or relationship to each other, resulting in a straight line that passes through the origin when graphed.
