How to read a graph?
A graph has two axes, the one running top to bottom (vertical or y axis) and one running right to left (horizontal or x axis). You can run your finger up the y axis to the point where it is at the same height as the point on the line you are interested in, and note the number on the y axis, then run your finger across to the point on the line you are interested in, then take your finger down to the x axis and note the number of that axis, then combine the two. For example, if the graph shows height on the y axis and time on the x axis, you go up the y axis to say, 23 cm, then across to the point on the line, then down to the x axis which is say, 12 hours, then you know that by 12 hours the plant (for example) had grown 23 cm.
Are the x-axis and the y-axis in any quadrant?
No the x-axis and y-axis are not in any quadrant. They go between quadrants.
Can you skip numbers on the x-axis on a graph?
You cannot do it as this will affect the shape of the graph. The x-axis, like the y-axis, must go in order. What is the point of them giving you values of x-axis if you can skip it?
How do you graph 5x-4y equals -15?
You are solving for x and y. If x is set equal to 1 and y is set equal to 4, then you have 5-20=-15. You can graph this by placing a point on the graph corresponding to x and y. That is, on the x axis you would go over 1 and on the y axis you would go up 5. Now if x is set equal to 5, then that is 25, so y must be set equal to 10. This is 25-40=-15. Then on the same graph, you go over 5 on the x axis and go up 10 on the y axis. Now you can draw a line between the two. All you have to do now is solve the equation for another set of numbers, and then put that point on the graph. With three points, you have sufficient information.
Does day go on the y axis and does time go on the x axis?
No, day goes on the x axis and time goes on the y axis.
