-20 is the answer I think
The answers are following
sol1 y = x-1
sol2 y= x+ 7
sol4 y = x+4
Step-by-step explanation:
Solution 1
Here we are going put the point in the given equation ( given in the options)
If the each point satisfies any equation, that will be the relationship between x and y.
Given points are (-3,-4) , (2,1) , (5,4)
Let us take the option C as y = x -1
-4 = -3-1
1 = 2-1
4=5-1
Putting each value in the given equation we get LHS and RHS are same for all points. so, C is the answer.
Similarly, option B is the answer of Solution 2
Each point satisfies the equation y = x +7
Solution 4
y = x +4
You are requested to check the options of Q3 once.
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= -2x -4
Step-by-step explanation:
slope: rise/run = 2/-1 = -2
y-intercept: -4
1/12 or decimal form 0.083 with repeating line
