You take the change in Y or dy and divide it by the change in X or dx. Slope equals dy/dx.

Slope = change in y/ change inx Slope is denoted as m in the following equationy=mx+b (called the y-intersept form)Where b is the y intercept, and x and y are the coordinatesTo solve for b, plug in the values for m, x, and y, and solve for b in the way you normally solve an algebraic equation
If you mean: y-3x = 5 then in slope intercept form y = 3x+5
first look and see if you graphed the lines between the two and the slope is m and the y-int is b .
plug in the slope(m) and coordinates (x,y) into the slope-intercept formula & solve for b.slope-intercept formula: y=mx+b
Solve the line equation for "y", to get it in slope-intercept form. You can immediately read the slope from this equation.Divide -1 by (slope of this first line) to get the slope of the second line - the one perpendicular to the given line. Write an equation for any line with this slope.
