Take the negative reciprocal of the lines slope you want it to be perpendicular to. For example y = 3x +2; perpendicular line slope is -1/3.

Any vertical line has an undefined slope. The equation of the vertical line is x = a where the x-intercept is a.

If you have any expression that defines a line, you can find the slope of the line. After you have found the slope of the line, you can then write an expression describing the line in slope intercept form. You can't define a slope-intercept form for any nonlinear equation, because the slope is always* changing; there are often several intercepts as well.

As for example if the slope is 3 and the y intercept is 6 then the equation is: y=3x+6

We know that its slope is negative, but without an equation or some points the line passes through we can't determine the actual value of the slope.

Write the equation of the line in the standrad form: y = mx + c The slope of this line is m The inverse of the slope is then 1/m. Note, that for a line perpendicular to the first, you need the negative inverse, not just the inverse. And the negative inverse of m is -1/m.

1. The slope of a flat line is smaller than the slope of a steep line.2. The slope of a flat line should be close to 0. 3. A negative slope means that the line mover down from left to right.
