find the gradient of the line passing through each of the following pairs of points a (5,-2) and b (2,1)

-1

Step-by-step explanation:

Gradient is y2-y1 divided by x2-x1

So:

gradient = 1-(-2)/2-5

= 1+2/-3

=3/-3

=-1

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.
