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>

The slope.
slope-intercept form is y= mx + b
Where:
mx is the slope
and b is the y-intercept.
Since the y-intercept isn’t an option, the correct answer would be slope.
The measures of the angles are 30, 60 and 90 degrees.
Explanation:
I assume the question should read "the measures of the ANGLES of the triangle are in the ratio 2:4:6.
If the angles are in the proportion 2:4:6, the measures of the angles have the same scale factor
x
. And, the sum of the measures of the angles of a triangle is
180
.
