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.
Find the gradient of the line passing through (a, b) and (0, c). Intercepts. The x-intercept of a line is the point at which it crosses the x-axis. The y-intercept of a line is the point at which it crosses the y-axis. In the diagram to the left the y-intercept is at A and the x-intercept at B. The second diagram shows a line parallel to the x-axis and it has a y-intercept at C. The third diagram shows a line parallel to the y-axis and it has an x-intercept at D. Equation of a straight line. When we plot points which satisfy the equation. y = 2 x + 1 we find that they lie in a straight line.
