The original equation we have is : <span>−x − 2y = −10
We need to isolate the x, which means that we need to get x alone on one side of the equation preferably in a positive form.
So, going back to the original expression:
</span><span>−x − 2y = −10
To make x positive, we will add x to both sides of the equation, thus, we get:
-2y = -10 + x
The next step is to eliminate the -10 from beside the x. To do this we will add 10 to both sides of the equation. When doing this we get:
x = -2y + 10
Based on this, the correct choice is A : -2y + 10</span>
4x + y = 7
y = -4x + 7
using y = mx + b
b being your y intercept, (0,7)

Answer:
the horizontal are called x-axis, while the vertical are called y-axis
Answer:
area after 8 years is 2156km²
Step-by-step explanation:
Area of forest=4900 km²
decrease in area in 1 year=4900km² × 7%
decrease in area in 1 year= 343km²
decrease area in 8 years=343km² × 8
=2744km²
Remaining area= (4900-2744)km²
=2156km²
