First, get the equation into the form y+=+mx+%2B+b
y+-+5+=+-2%2A%28x+%2B+5%29
Add 5 to both sides
y+=+-2%2A%28x+%2B+5%29+%2B+5
y+=+-2x+-+10+%2B+5
y+=+-2x+-5
m+=+-2
The slope is -2
To find a point on the line just randomly pick any value for either
x or y
I'll say x+=+-15
y+=+-2x+-+5
y+=+-2%2A%28-15%29+-+5
y+=+30+-+5
y+=+25
Therefore, (-15,25) is a point on the line

To identify the slope, we must convert the equation into this form: y=mx%2Bb
The value of m is the slope.

y-5=-2%28x%2B5%29

Steps to determine slope:
1. multiply -2 by each term inside the parenthesis.
2. add 5 on both sides of the equation.
3. the coefficient of x is your slope. Remember, when m = full number, it's the same as having that number over 1. That is how you'll know what the rise/run is.

Steps to identify one point on the line:
1. substitute an integer (any number) for the x in the equation.
2. solve for y.
3. the integer and the value of y would be your one point on the line.

I'll let you complete the problem. If you follow the steps carefully, you will get your answers.
