hatch marks
The definition is any chart where one or more points lie off the straight line joining the other points.
A truncated graph has on of its axes cut off or "truncated"
y >= -3 + xThis is the same asy>= x-3Start off by sketching the regular graph of y=x-3 (should look the same as the graph of y=x but shifted down 3 places so that the y intercept is at the point (0,-3)).Now just shade the half of the graph where y is greater (so shade in the positive direction for y above the graph of the line).In the end you should have the graph of a diagonal line shaded over the top.***Note: You will draw your graph with a solid line because because the question says GREATER THAN OR EQUAL TO. If you ever get a graph that is strictly greater than or strictly less than, instead of drawing a solid line, draw a dotted line, to show that you're not including the values where y is equal to your function.If you get y> shade in the positive y direction and use a dotted line.................y< shade in the negative y direction and use a dotted line.................y>= shade in the positive y direction and use a solid line.................y
It is the same as the original reflected in the line whose equation is y=x. You will get the same effect if you imagine lifting the graph off the paper, and flipping it clockwise through 180 degrees and then putting it down so that the y-axis is where the x-axis was and the x axis is where the y-axis was.
A good place to start is at a website called www.superteacherworksheets.com/graphing.html . Once you are there you select the line graph section and start off by clicking on the beginner line graph worksheets. As you get better you can then work on intermediate and advanced level line graphing worksheets provided on the same webpage.
Yes
Because ever line is different and you can only read off your line in the graph.
In a graph, the rise of a line usually represents an increase of some quantity. What that quantity is must be read off the graph's axes.
Mark off your number line in tenths. That's 2.2 and 3.1

a non linear graph pretty much means the points on the graph do not create a straight line. in order for a graph to be linear both the x axis and y axis have to increase/decrease at a constant rate, while in a non-linear graph when you connect the point it creates a line that isn't straight. however, in experimental data if the points are a bit off, but still in one general area, it can be considered linear.

They convey similar information so neither has any significant advantage over another. Line graphs are probably better when there are many data points to be plotted and bar charts when there are only a few. This is particularly important if you do not wish naive users to interpolate between data points. Stacked bars are probably better for illustrating levels as well as shares of the total.
