_________
Graph in the picture!
- y > 2x + 10 = y - 2x - 10 > 0
- y < -x - 3 = y + x + 3 < 0
we have
the equation of the line is
the points are
<u>Method 1</u>
we know that
A relationship between two variables, x, and y, represent a direct variation if it can be expressed in the form or
In this problem we have a direct variation
The constant of proportionality k is equal to the slope of the line
so
therefore
<u>the answer is</u>
the slope of the line is equal to
<u>Method 2</u>
we know that
the formula to calculate the slope between two points is equal to
we have
substitute in the formula
therefore
<u>the answer is</u>
the slope of the line is equal to
