This is true as long as the slope of the line is constant, if it is a straight line and doesn't curve, then yes it doesn't matter which points are chosen.
A.True
To find the slope of any line y = f(x) differentiate with respect to x: slope = dy/dx; the slope at any point can then be found by substituting the value of the x coordinate of that point. If you mean how to find the slope of a straight line: slope = change_in_y/change_in_x Taking any two points on the line (x0, y0) and (x1, y1) this becomes: slope = (y_of_first_point - y_of_second_point)/(x_of_first_point - x_of_second_point) → slope = (y1 - y0)/(x1 - x0) As it doesn't matter which is chosen as the first point, the slope can also be written as: slope = (y0 - y1)/(x0 - x1)
Calculate the difference of the y-coordinates, and divide it by the difference of the x-coordinates. That is the slope.
It work out as a 1/2 or 0.5
Points: (-1, -1) and (3, 15) Slope: 4
Apex:true
Slope of line: (y2 -y1)/(x2-x1)
true
A.True
Absolutely not, because the slope of the line does not change no matter its location on the x or y axis.
The slope is calculated as: y1-y2/x1-x2 given two sets of points
Points: (-3, -1) and (3, -2) Slope: -1/6
You need two points before you can calculate the slope.
No. If you have more than two points for a linear function any two points can be used to find the slope.
Choose two distinct points from the table and designate their coordinates as x1, y1 and x2, y2. The slope of the line then will equal (y2 - y1)/(x2 - x1).
Points: (x, y) and (x, y) Slope: y1-y2/x1-x2
