How do you know when there is positive correlation on a graph?
when the points on the graph are close to each other;)
When the coefficient of x is positive the line what?
Has a positive gradient (in a y=mx+c graph)
Which way does a parabola open when the coefficient of its x2 term a is positive?
It is like the letter U.
Can slope k of a direct variation be positive?
The slope of the graph of a direct variation is always positive.
Which way does a parabola open when the coefficient of its x2term a is positive?
Upwards: it is cup shaped, not cap shaped.
Which side of a graph 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.
Which graph shows a positive correlation between x and y?
Any graph where, from left to right, the slope goes upward (assuming the axes are labelled in the standard way).
Can you include Excel graphics in your PPT presentation slides?
Yes. An easy way to do so is to open Excel and copy the graph you want to use in your presentation. Open PowerPoint and paste the graph where you want it displayed.

If a is positive which way does the parabola open?
Upwards like a letter U
Which way does a parabola open when the coeffienct y2-term a is positive?
right
What is the correlation on a graph?
a correlation on a graph is when the line of best fit is positive, negative or none.
If a is positive but gets close to o what happens to the graph?
The answer depends on what the graph is meant to represent.
If a graph of distance versus time is a straight line the graph shows what relationship?
it is a positive relationship
What is a 4 quadrant graph used for?
to graph not only positive numbers, but negative ones as well
When the coefficient of x is positive the line what?
Has a positive gradient (in a y=mx+c graph)
What is the trend of a 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.
