Answer:
see explanation
Step-by-step explanation:
Using the rules of exponents
⇔ 
and 
= 1
Substitute the values of x into 
x = 0 → 
= 1 ⇒ a = 1
x = 2 → 
= 
= 
, hence
b =
x = 4 → 
= 
= 
, hence
c =
Answer:
y = -13x + 55
Step-by-step explanation:
perpendicular formula : m1 × m2 = -1
y = -13x + 4
now we take the grafient of the equation which is 13 :
m × 13 = -1
m = -13
so now we hv a new gradient then we can find the equation use the formula y = mx + c :
m = -13 point = ( 4 , 3 )
sub them into the formula,
3 = -13 (4) + c
3 = -52 + c
3 + 52 = c
55 = c
c = 55
now we rewrite again the c and the m to become a complete equation : y = -13x + 55
