For question 4: you have to do (y2 - y1) divided by (x2 - x1) to get the rise over run...

5-2
——. = 3/4
11 - 7

For question 5: input the values of x,y and the gradient into the equation of a line.....

y = mx+ c

-8 = 3(-2) + c

-8 = -6 + c

-2 = c

therefore:

y = 3x - 2

Hope this helps! Any questions let me know :)

Answer:

<em>Rate of Change = 4</em>

Step-by-step explanation:

The starting point (x=0) is (0, -2)

The ending point (x=2) is (2, 6)

The distance between the two points in rise over run terms is 8/2

$\frac{8}{2} =4=rate$
