1. The slope of the line passing through the points (1,1) and (-1,0) is \(m = \frac{0 - 1}{-1 - 1} = \frac{-1}{-2} = \frac{1}{2}\).<br />2. The slope of the horizontal line through (-1,0) is 0.<br />3. The slope of the vertical line through (-1,1) is undefined.<br />4. The equation of the line passing through (-1,1) with slope \(-\frac{1}{2}\) is \(y - 1 = -\frac{1}{2}(x + 1)\).
Explicação
## Step 1:<br />To find the slope of a line passing through two points, we use the formula:<br />### \(m ={y_2 - y_1}{x_2 - x_1}\)<br />where \(m\) is the slope, and \((x_1, y_1)\) and \((x_2, y_2)\) are the coordinates of the two points.<br /><br />## Step 2:<br />For a horizontal line, the slope is 0 because there is no change in the y-coordinate.<br /><br />## Step 3:<br />For a vertical line, the slope is undefined because there is no change in the x-coordinate.<br /><br />## Step 4:<br />To write the equation of a line, we use the point-slope form:<br />### \(y - y_1 = m(x - x_1)\)<br />where \(m\) is the slope and \((x_1, y_1)\) is a point on the line.
