What is the gradient of the graph shown
Keith_Richards [23]

9514 1404 393

Answer:

  3

Step-by-step explanation:

The gradient is the ratio of "rise" to "run". Here, it appears the line crosses the y-axis at y = -1. It appears that it also crosses the grid intersection at (1, 2). This represents a "rise" (change in y) of (2 -(-1)) = 3, for a "run" (change in x) of (1 -0) = 1. Then the gradient is ...

  m = rise/run = 3/1 = 3

The gradient of the graph is 3.

Value Equation:: 1.5h+0.5s=78.50

Multiply thru the Quantity Equation by 15
Multiply thru the Value Equation by 10.

15h + 15s = 15*87
15h + 5s = 785</span>Subtract and solve for "s":<span>10s = 520
