What else can I help you with?
Why can you use any two points on a line to find its slope?
You can use any two points on a line to find its slope because the slope represents the rate of change between two points. By selecting two distinct points, you can measure the vertical change (rise) and the horizontal change (run) between them. The slope is calculated as the rise divided by the run, which remains constant for any two points on a straight line. This characteristic defines the linear relationship represented by the line.
Why is the slope between any two points on the straight line always to same?
The slope between any two points on a straight line is constant because a straight line represents a linear relationship between the two variables. This means that the rate of change remains consistent regardless of which two points you choose on the line. Mathematically, the slope is calculated as the change in the vertical direction (rise) over the change in the horizontal direction (run), and for a straight line, this ratio does not vary. Therefore, the slope remains the same for all pairs of points on that line.
How can you find the unit rate of constant of proportionality for a relationship represented in a graph?
To find the unit rate or constant of proportionality from a graph, identify two points on the line that represents the proportional relationship. Calculate the change in the y-values (output) and the change in the x-values (input) between these two points. The constant of proportionality is then found by dividing the change in y by the change in x, resulting in the slope of the line. This slope indicates the unit rate of the relationship.
Is the slope of a line constant true or false?
True. The slope of a line is constant, meaning it remains the same regardless of the two points chosen on the line. This consistency is what defines a linear relationship, where the change in the y-coordinate is proportional to the change in the x-coordinate. In contrast, the slope of a curve can vary at different points.
The runs is the change between two points along line?
The run (not runs - which means diarrhoea) is the horizontal change between two points.

What Is the horizontal change between two points on a line.?
Run
The runs is the change between two points along line?
The run (not runs - which means diarrhoea) is the horizontal change between two points.
When the rate of change between any two points on a line is negative What is the slope of the line?
No
What is nonvertical line is the ratio of the vertical change to the horizontal change between any two points on a line?
The slope.
The run is the what change between two points along a line?
yea
What is the change between two points on a line?
It is the fact that their coordinates are not the same.
The slope of a line is the ratio of the?
vertical change to the horizontal change between any two points on the line. study island.
A line is the locus of points which what?
A line is the locus of points such that the gradient (slope) between that point and one fixed point in the plane is a constant. Technically, that definition does not include a vertical line because its gradient is not defined! You could get around that this by requiring that either the gradient is a constant or, if it is undefined, then the inverse gradient (dx/dy) is constant.
Is the rate of change between any two points on a line?
That's called the line's slope.
How do you find the constant rate of change on graph?
You measure the change in the vertical direction (rise) per unit change in the horizontal direction (run). The rate of change is constant between A and B if AB is a straight line. Take any two points, A = (xa, ya) and B = (xb, yb) then the average rate of change, between A and B = (yb- ya)/(xb- xa).
