Answer:
Gradient = -1
Step-by-step explanation:
Since the graph shows a downward-sloping line, then it means that it will have a negative gradient. From point (-4, 0), the next point occurs at (-3, -1). This means that the point moved 1 unit down (-1 ), and 1 unit towards the right.
Therefore, the gradient is: -1/1 or -1.
For your reference: to prove that my answer is correct, we can substitute the points into the slope formula:
m = (y2 - y1)/(x2 - x1)
m = [-3 - (-4)] / (-1 - 0)
m = (-3 + 4) /(-1 - 0)
m = 1/-1 = -1
