When doing linear regression if the correlation coefficient is positive the slope of the line is negative?
False.
What does a function on a graph look like?
A function is just a fancy name for a math problem. It could be a straight line or it could be a parabola or even some thing else. The key to knowing what it looks like is the leading coefficient. What is the highest power of x? Is it positive or negative? An x with the power of one will be a straight line at an angle.
What is the connection between slope in a linear function and the a coefficient in a quadratic?
The slope of a linear function is the coefficient of the x term. The sign of this number will determine if the line increases as x increases, or decreases as x increases (slopes up or down). The magnitude of the slope determines how steep the line is (how fast it increases).The coefficient of the x2 term in a quadratic function will tell you similar characteristics of the parabola. The sign will tell you if the parabola opens up or down. The magnitude of the coefficient tells you how steeply the graph changes.
Which is not a condition that must be met before you can use the quadratic formula to find the solutions?
"The coefficient of the x^2 term must be positive" is a condition that does not have to be met.
What is a coefficient term in math?
OK, say you have a variable like X. 3X 3 is the variable X's coefficient
When the coefficient of x is positive the line is vertical?
no, false
When the coefficient of x is positive the line goes up and to the left goes down and to the left is vertical or is horizontal?
When the coefficient is positive, the line goes up and to the right.
When the coefficient of x is positive the line what?
Has a positive gradient (in a y=mx+c graph)
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.
When the coefficient of x is positive the line is?
Sloping upward (from bottom left to top right).
Is the slope of a line the coefficient of the x-term in the line?
Yes, the slope of a line is the coefficient of the x-term in the line.
Which statement best describes a line in slop-intercept form when the coefficient of the x-term is positive?
The line will be going 'uphill' from left to right
Is the slope of a line the coefficient of the x-term in the line's equation?
True.
In the slope-intercept equation for a line the coefficient of the x-term gives the .?
The coefficient of the x term gives the gradient of the slope.
The appears in the equation of a line as the coefficient of the variable x?
slope
When the coefficient of x negative the line?
Goes down and to the right
When the coefficient of x is negative the line?
goes up and to the left
