Question

What is slope? How can you determine slope from a graph?

Answer 1

you got a graph?

Answer 2

Choose any two points on the line, and plug them into the slope formula.

Answer 3

@satellite73 no I dont have a graph there just general questions haha

Answer 4

So do what I said then.

Answer 5

To calculate the slope of a line you need only two points from that line, (x1, y1) and (x2, y2).

The equation used to calculate the slope from two points is: On a graph, this can be represented as:


There are three steps in calculating the slope of a straight line when you are not given its equation.

Step One: Identify two points on the line.
Step Two: Select one to be (x1, y1) and the other to be (x2, y2).
Step Three: Use the slope equation to calculate slope.

Answer 6

slope is a surface of which one end or side is at a higher level than another; a rising or falling surface.

Answer 7

the slope is the gradient od a line at a given point.

For a straight line the slope is the same at all points

For a curved line the slope at a given point is the given by the tangent to the curve.

Numerically it is given by 'change in y / change in x'

for a straight line it is calculated by the formula that @student_basil gave above.

(it is more normally written as (y2-y1)/(x2-x1) but the result is the same)

For a curved line you need to use calculus, and the slope is given by the first derivative of the curve (dy/dx) at the point.

It is also known as the 'rate of change' of th ecurve at that point.

Thank you everyone
