<PRE><B>Question 626116</B>
Plot the straight line graph:

5x + 2y = -2

Subtract 5x from each side of the equation.

5x + 2y - 5x = -2 - 5x

Combine like terms:

5x - 5x = 0

We now have:

2y = -2 - 5x or

2y = -5x - 2

Divide each side by 2

2y/2 = -5x/2 - 2/2

y = -5x/2 - 1


From the above we get the following x and y coordinates:

(-4,9)

(-2,4)

(0,-1)

(2,-6)

(4,-11)


The Slope Formula:

(y2 - y1)/(x2 - x1)

(-6 - (-1)/(2 - 0)

-6 - (-1) = -6 + 1 = -5

2 - 0 = 2



The Slope (m) = -5/2 (or -2.5)
