How can you find the slope and the y-intercept of a linear equation from a table of values?<\/p>\n\n\n\n

The Correct Answer and Explanation is :<\/strong><\/mark><\/p>\n\n\n\n

To find the slope and the y-intercept of a linear equation from a table of values, follow these steps:<\/p>\n\n\n\n

Step 1: Understand the Table<\/h3>\n\n\n\n

A table of values typically lists pairs of x and y coordinates. For example:<\/p>\n\n\n\n

x<\/th>y<\/th><\/tr><\/thead>
1<\/td>2<\/td><\/tr>
2<\/td>4<\/td><\/tr>
3<\/td>6<\/td><\/tr>
4<\/td>8<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

Step 2: Identify the Points<\/h3>\n\n\n\n

From the table, you can identify several coordinate pairs (x, y). For instance, using the first two pairs (1, 2) and (2, 4).<\/p>\n\n\n\n

Step 3: Calculate the Slope<\/h3>\n\n\n\n

The slope (m) of a linear equation is calculated using the formula:<\/p>\n\n\n\n

[
m = \\frac{y_2 – y_1}{x_2 – x_1}
]<\/p>\n\n\n\n

Using the two points from the table:<\/p>\n\n\n\n

    \n
  • Let ( (x_1, y_1) = (1, 2) ) and ( (x_2, y_2) = (2, 4) )<\/li>\n<\/ul>\n\n\n\n

    Substituting these values into the formula gives:<\/p>\n\n\n\n

    [
    m = \\frac{4 – 2}{2 – 1} = \\frac{2}{1} = 2
    ]<\/p>\n\n\n\n

    Step 4: Find the Y-Intercept<\/h3>\n\n\n\n

    The y-intercept (b) is the value of y when x = 0. If the table does not directly include x = 0, you can use the slope-intercept form of a linear equation ( y = mx + b ) to solve for b.<\/p>\n\n\n\n

    Using one of the points, let\u2019s use ( (1, 2) ):
    [
    2 = 2(1) + b
    ]
    [
    2 = 2 + b \\implies b = 0
    ]<\/p>\n\n\n\n

    Final Equation<\/h3>\n\n\n\n

    Now, you can express the linear equation as:<\/p>\n\n\n\n

    [
    y = 2x + 0
    ]<\/p>\n\n\n\n

    Conclusion<\/h3>\n\n\n\n

    In summary, by selecting pairs of points from the table, calculating the slope using the difference in y-values over the difference in x-values, and then determining the y-intercept by substituting known values back into the slope-intercept equation, you can effectively derive the linear equation from the table. The final form ( y = mx + b ) summarizes the relationship between x and y, where ( m ) is the slope and ( b ) is the y-intercept.<\/p>\n","protected":false},"excerpt":{"rendered":"
