5/4 is a just a single point on a numbered line. That point is its graph.

1. Draw and label your x and y axes 2. Choose a non-zero x value 3. Calculate y value 4. Place ruler on (0,-2) and the coordinate you just calculated 5. Draw line to edges of graph
18 degrees is 5% on a circle graph.
Well, that isn't a proper equation but if the equation is, y=4x(+/-)9... First: Put the "b" value into your graph. The "b" value is on the y-intercept, in this case, it would be (+/-)9. If it is +9, put it 9 values up on the y-axis. Vice-versa if negative. Second: The 4x would be the slope. The 4 represents the "a or m" value. Since the slope is 4, then you would start at the (+/-)9 and go UP:4 and OVER:1. This is the Rise Over Run technique. The reason you go over 1 is because 4=4/1 the 4 represents rise and the 1 represents run. (If the "m"value was 1/4 then you'd go up 1 and over 4). Lastly: Repeat that method over and over again until you run out of room on your graph. Then make a line connecting each dot and at the end of each line put arrows pointing outward displaying that the slope will be infinite.
4x+5y = 7 5y = -4x+7 y = -4/5x+7/5 in slope intercept form So the slope of the perpendicular line is plus 5/4
Flip the graph over the x and y axes. one first, then the other. All coordinates will then be (-x, -y).
