Find the area of all the sides and then divide each area by two. add them all up to get your answer.
Its either 3 or 2
the third way matches only if there's another reference line
I'll go with 3
Opposite number is the same number with the opposite sign:
So the opposite of

is

, since the original number is positive
opposite of

is

, since the original number is negative
The equation in the slope-intercept form is:
y = (1/2)*x + 3
<h3>
How to write the equation?</h3>
A general linear equation is:
y = a*x + b
Where a is the slope and b is the y-intercept.
To get the slope, we need two points on the line, by using the graph we can identify the points: (0, 3) and (2,4)
Then the slope is:

And we also can see that the y-intercept is y = 3, because of the point (0,3)
Then the line is:
y = (1/2)*x + 3
