yes the number 8 has a vertical line of symmetry. and depending on how you draw it also a horizontal line of symmetry.
You draw a vertical line at x=7. Does not matter what y value you pick, x is always 7. So find 7 on the x axis and draw a vertical line that is perpendicular to the x axis at the point (7,0)
draw a line vertical from where strain is equal to 2.5%. where it hits your stress vs. strain curve, draw a line from there to the origin the slope of that line is your Es or secant modulus
A horizontal line is perpendicular to a vertical line.
-- Label the vertical (' y ') axis ' w '.-- Draw a horizontal line on the graph, passing it through the pointon the vertical axis where w=5.-- Draw gigantic light 'X's, or shadows or slanty lines or squiggles, everywhereabove the horizontal line, indicating that every point in that infinite half-planeabove the line, as well as every point on the line itself, is a solution of the inequality.
