when the points on the graph are close to each other;)
Has a positive gradient (in a y=mx+c graph)
The slope of the graph of a direct variation is always positive.
it is the use of graphs for example bar graph and picto graph
A circle graph is a pie chart
when the points on the graph are close to each other;)
a correlation on a graph is when the line of best fit is positive, negative or none.
The answer depends on what the graph is meant to represent.
Bar graph.
it is a positive relationship
to graph not only positive numbers, but negative ones as well
Has a positive gradient (in a y=mx+c graph)
The trend of a graph is the slope of any line on the graph that indicated a positive or growth factor and/or a negative or decaying factor. If the slope goes negative, the graph's line will go down thus indicating decay. If the slope becomes positive, the graph's line will go up thus indicating growth.
Bar graph and pictograp are ploted on a horizontal line and in a positive quadrate
This depends on what the graph represents. If it is a graph of velocity on the vertical and time on the horizontal, then if acceleration is at a constant rate, the graph will be a straight line with positive slope (pointing 'up'). If acceleration stops, then the graph will be a horizontal line (zero acceleration or deceleration). If it is deceleration (negative acceleration), then the graph will have negative slope (pointing down).
For a straight line graph, if the equation of the graph is written is the slope-intercept form, then the line goes up and to the right when the coefficient of x is positive.
You can draw a graph any way you want to, as long as you label both axes clearly, to show which direction is positive and which direction is negative, on each axis. Typically ... the way people are accustomed to looking at a graph ... numbers on the x-axis are positive on the right half, and numbers on the y-axis are positive on the top half.
