Question

What is the gradient of the blue line X? Please help, thank you <3

Answer 1

Gradient is -3.

Explanation:

Start at (-2, 2). Go down 6 units, then right 2 units, to (0, -4). So the gradient (slope) of this line is -3.

Answer 2

gradient = -3

Step-by-step explanation

Gradient is the rate of change of y by rate of change of x.

`\sf Gradient: (y_2 - y_1)/(x_2-x_1)` where (x1, y1), (x2, y2) are points

Here take two points which the lines crosses,

• (-1, -1) and (-2, 2)

Now find the gradient:

`\sf Gradient: (2 -(-1))/(-2-(-1)) = (2+1)/(-2+1) = (3)/(-1) = -3`
