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).
No, y=8 is a fixed value. A linear equation would look something like y=x+8 - That would produce a straight line graph if the values of x & y were plotted against each other on a graph.

Just label one axis x and the other axis y. Voila!! x y graph!

To graph them, you need to put them into the formula y=mx+b. If x+y=8 subtract x to get y=-x+8. 8 is the y-intercept and your line should be heading downward from left to right.
y=x+8 is a linear equation. Y is the Y point on a graph, X is the slope, and 8 is the y intercept
To translate the graph y = x to the graph of y = x - 6, shift the graph of y = x down 6 units.
The graph of [ x=8 ] is a vertical line through the point 8 on the x-axis. It never touches the y-axis, and has no y-intercept.
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.
No, y=8 is a fixed value. A linear equation would look something like y=x+8 - That would produce a straight line graph if the values of x & y were plotted against each other on a graph.
First, reflect the graph of y = x² in the x-axis (line y = 0) to obtain the graph of y = -x²; then second, shift it 3 units up to obtain the graph of y = -x² + 3.
y=(1/4)x represents a slope-intercept equation. You graph it by inserting a value for x, like 8, and then solving the equation to see what y equals. In this instance, you can see that if x=8, then y=(1/4)*(8) and therefore, y=2. So, you graph x=8 and y=2 for a single point. To get a second point, insert another x value, like 4, and that will lead to another y value; 1. The 2 points here are (8,2) and (4,1); to get the line, simply draw a line that goes through both the points.
