Answer:
Y = (-3) *X - 10
solution for Y =0 ---> X = -10/3
Step-by-step explanation:
Two points:
(Y0 ; X0) = (-4 ; 2)
(Y1 ; X1) = (-2 ; -4)
There is only one line which pass for both of them, his general expresion is:
y = a*x + b --- (1)
Calculating "a": is the pending of the line.

Calculating "b":
Since every point who belongs to the line satisfied the (1) expresion, we can use it for the point (Y1 ; X1) :

<u>Final expresion</u>
Replacing in (1): 
Solutions:
24 and 42, I got this by multiplying 5 and 2 then doing the same thing to 7 and adding the sums. I used this method to find the perimeter of 10 and 12 as well.
Answer:
No solution exists
Step-by-step explanation:
12x12.5=150
Steps:
1. convert 12.5 into a fraction: 25/2
2. also convert 12 into a fraction: 12/1
3. multiply 25/2x12/1=150.
Hope I helped! :D
