two points A(-3;-8)AND B(2;7)LIE ON A STRAIGHT LINE CALCULATE THE GRADIENT OF LINE AB
slope = [ 7 - (-8)] / [ 2 - (-3) ]
= 15/5
= 3
To calculate the gradient (slope) of the line AB, you will need to use the formula:
Gradient (m) = (y2 - y1) / (x2 - x1)
where (x1, y1) and (x2, y2) are the coordinates of points A and B respectively.
In this case, the coordinates of point A are (-3, -8) and the coordinates of point B are (2, 7).
Using the formula, we can substitute the values:
Gradient (m) = (7 - (-8)) / (2 - (-3))
= (7 + 8) / (2 + 3)
= 15 / 5
= 3
Therefore, the gradient (m) of the line AB is 3.
