The constant shelling did not bother him as much as the loss of his food. As the siege wore on, fewer and fewer horses, mules, and dogs were seen wandering about Vicksburg. Shoe leather became a last resort of sustenance for many adults.
If the graph of a quadratic function has two x-intercepts, then the line of symmetry is the vertical line through the midpoint of the x-intercepts. The x-intercepts of the graph above are at -5 and 3. The line of symmetry goes through -1, which is the average of -5 and 3. (-5 + 3)/2 = -2/2 = -1.
To find the slope-intercept form y = mx + b of a line given any 2 non-coinciding points on the same coordinate graph, we need to find the line's slope m and its y-intercept b. â¦ To find the slope, subtract one point's y-coordinate from the other point's y-coordinate.
