How to find a positive slope.
Are all slopes positive?
No. To get a positive slope, the rise must go up and the run goes to the right, or the rise must go down and the rise must go to the left.
How to find a negative slope.
Well what about a negative slope?
To get a negative slope, the rise must go up and the run go to the left, or the rise must go down and the run go to the right.
Summary
So a linear equation is a equation for a line. To find the slope, you must find the rise over run. To find the y-intercept, you find what point the line crosses the y-axis at? That's so simple !
Exactly !
