I am sure but I am going with Property if equation . this is say if x =2 then 2 x y = 2y .
Move the decimal's place 7 times to the right. That means that 12.5*10^7 = 125*10^6. Now add 6 zeros: 125,000,000.
You can actually use a calculator to check your answers if it is allowed.
Answer:
Y= 2x+2
Step-by-step explanation:
line equation is y=mx +c
m is the gradient = 2
We are given an x and y value
X= 1
y= 4
substitute that into the equation:
4= 2(1) +c
2=c
Put all the equation together:
Y= 2x+2
