Answer:
a=4, b=144
Step-by-step explanation:
Let's take two random points of X and y and simplify the equation containing a and b; let's go,
Points (4,-5); (6,0)
For (4,-5)
-5= a -b/ (4 x4)
-5= a- b/16; -80= 16a - b[ by multiplying through by 16]
For (6,0);
0= a -b/ ( 6x6) ; 0=a- b/36
Multiplying through by 6, we have:
0= 36a-b; 36a=b;
So the modified equation of a and b are;
b=36a
b=16a+ 80[ modifying the derived expression moving b to the left]
So if we equate both expressions,
We have:
36a=16a+80;
36a-16a=80, 20a= 80; a= 80/20= 4;
a=4;
Substituting the value of a into any expression for b; we have
b= 36a= 36x4 =144
Hence a=4, b= 144
Y=a-b/x².
Using first column: x=1, y=140
140=a-b
Using last colimn: x=6, y=0
0=a-b/36, b=36a
140=a-b=a-36a=-35a
a=-140/35=-4
b=36a=36×(-4)=-144
Answer: a=-4, b=-144
