y=mx+b
slope= rise run If its already graphed then you find where the line meets the y- line ( thats the b in the equation) from there you go up or down on the y- line to the point where the line next meets directly over another vertical line on the grid, the number of times you moved up or down is the "rise" in the equation for slope. After finding rise your move left or right from that point on the y-line until you meet the point where the line is and that will be the run. That fraction or number once you simplify the equation is you slope. Hope that helps.
Easy the equation will always be y=mx+b
mx is the slope in the equation and b is the y intercept and always remember rise over run ;
The slope of a line is classified based on its steepness and direction, determined by the ratio of rise to run. A positive slope indicates a line that rises, a negative slope indicates a line that falls, a zero slope indicates a horizontal line, and an undefined slope indicates a vertical line. The slope can be calculated using the formula m = x 2 − x 1 y 2 − y 1 .
