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.
Examples > Algebra > Linear Equations > Finding X and Y Intercepts. To find the x-intercept, substitute in for and solve for . Since is on the right side of the equation, switch the sides so it is on the left side of the equation. Since does not contain the variable to solve for, move it to the right side of the equation by subtracting from both sides. Multiply each term in by.
