Y = mx + b is in the form of slope-intercept.
From the equation given, y + 2x = y - 2, we can convert it in the format of the slope intercept form and it depends we can came up to that form.
y + 2x = y -2
y - y = -2x - 2
0 = 2x + 2
x = -1
Unfortunately, the form y = mx + b is impossible to achieve.
Answer:
1) The value of c is given by

2) The value of k is given by

Step-by-step explanation:
Given that function g is defined by
, where c is a constant.
To find c:
Also given that value of g(x) at x=0.5 is equal to -1
ie., 
At x=0.5






Therefore 
2) Given that function h is defined by
, where k is a constant.
To find k:
Also given that value of h(x) at x=20 is equal to 65
ie., 
At x=20



Therefore 
Answer:
0.25
