The graph of the equation y=8 is a horizontal line through the y-intercept of 8. This is because since y=8, any point on the graph will have a y-coordinate of 8. This is why it is a horizontal line through (0,8).
The graph of y = x - 8 is a straight line. The slope of the line is 1, and it intersects the y-axis at the point y = -8.
When you plug in x = 0, you get y = 8. When you plug in x = 8, you get y = 0. So the graph of y = x - 8 (which is clearly linear, a straight line, because it only has x to the first power) is the graph of the straight line that goes through the points (0,8) and (8,0).
The line 8x-8=0 is the same as x=1. The graph looks like a vertical line that intersects the x axis at x=1.
The line is vertical on the graph. Its slope is infinite.

Answer this question… What is the line of symmetry of the graph of the equation ? A. x = -2 B. x = -4 C. x = -16 D. x = -8
The first thing to not is that the only powers of x and y in the equation are one. That means the graph is a straight line. Any two points on a straight line determine the whole of the straight line. So solve the equation for x = 0 and for y = 0. Thus, when x = 0, the equation becomes y = 8 - 0 ie y = 8 so (0, 8) is a point on the graph. and when y = 0, the equation becomes 0 = 8 - x ie x = 8 so (8, 0) is another point on the graph. Join up these two points and extend the line further in both directions.
The line is vertical on the graph. Its slope is infinite.
The graph on figure 8-8 is not shown here so there really is not any way to know which one is correct. Without his information the answer is not able to be known.
