When the coefficient of x is positive the line what?
Has a positive gradient (in a y=mx+c graph)
What is the meaning of negative coefficient of x?
In the form y=mx+b, b is the y-intercept and m is the coefficient, so if an equation has a negative coefficient, m<0. As a graph, the slope of the line is negative.
When does the graph of a line go down to the right?
Amongst polynomial graphs, it is when the coefficient of the highest power of the variable (x) is negative.
When you graph a quadratic function what will the shape of the graph be?
A parabola. An arch opening either north or south of the x-axis depending on the sign of the coefficient (negative opens down, positive opens up).
What is a correlation coefficient of 0.0731?
This means there is no correlation between the points on a graph. There is no linear relationship between the x and the y values at all. 0.98 is usually deemed to be an acceptable r2 value
How does the leading coefficient a affect the graph?
idk
What happens to the graph as the coefficient increases?
Most graphs will become steeper as the coefficient increases.
The graph of a line goes up and to the right when?
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.
The graph of a line goes down and to the right when?
the coefficient of x is negative
When the coefficient of x is positive the line what?
Has a positive gradient (in a y=mx+c graph)
What is the meaning of negative coefficient of x?
In the form y=mx+b, b is the y-intercept and m is the coefficient, so if an equation has a negative coefficient, m<0. As a graph, the slope of the line is negative.
What does a strong negative correlation coefficient mean?
The graph follows a very strong downward trend. Would have helped if you specified which correlation coefficient; there are different types.
What is the coefficient of x in the equation of a graph that has slope 0?
y=mx has a slope of m, if the slope is 0, m must be 0. So the coefficient of x is 0.
When an odd function has a negative leading coefficient what happens to the graph?
the left end of the graph is going in a positive direction and the right end is going in a negative direction.
What does the slope of a friction vs weight graph mean?
the slope is the coefficient of friction. look at the equation of the graph as apply it to any of the friction problems your teacher gave you.
Which statement holds true for absolute value functions The absolute value determines the direction in which the graph opens. The coefficient determines the line along which the graph is symmetrical.?
Neither statement is true. The graph of the absolute value of a function which is always non-negative will be the same as that of the original function and this need not open in any direction. Also, the graph of y = abs[x*(x-1)*(x+2)] is not symmetrical so there is no coefficient which will determine a line of symmetry.
When does the graph of a line go down to the right?
Amongst polynomial graphs, it is when the coefficient of the highest power of the variable (x) is negative.
