so his change would be $10
Answer:

Step-by-step explanation:
The given equation is written in the form of y=mx+c (where m is the gradient and c is the y-intercept).
Thus, gradient of given equation= -⅔
The products of the gradient of perpendicular lines is -1.
(Gradient of line)(-⅔)= -1
Gradient of line

Hence, m=
.
Subst. m=
into the equation:

To find the value of c, substitute a pair of coordinates into the equation:
When x= -4, y= 2,

Thus, the equation of the line is
.
Answer:
a-b=12
Step-by-step explanation:
(a²-b²)/(a+b) = 12
(a-b)(a+b)/(a+b)=12
a-b=12
