Solving equations using a graph such as y=3x+6. The "6" is your y-intercept, so you would move 6 spaces up on the graph, and then plot that. Then you would move three spaces up and one to the right, since 3x is really 3/1. You would continue doing that. If you wanted to move down, you would just move using inverse operation. So you would plot 3 spaces down and 1 to the left. -3/-1 which is the same thing as 3/1. The formula for slope is y=mx +b. Hope this helped!

Formula for slope m is (y2 - y1)/(x2 - x1).
Point Slope Formula: y-y1 = m(x - x1)
The formula for finding the slope of the line is this: m = (Y2-Y1)/(X2-X1)
The formula for the slope of a line in mathematics is m = y2 - y1/x2 - x1. The slop of the line describes the steepness so a higher value slope means a steeper slope.
the slope formula is y=mx+b slope-intercept form of an equation of a line. where m=slope and b=the y-intercept
