How do you write an equation in slope intercept form if there is no slope?
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.
When does the equation of a line in slope-intercept form look just like its equation in point-slope form?
When it is a line through the origin.
What is the general form of a line written in slope-intercept form?
It is: y = mx+b whereas m is the slope and b is the y intercept
What is the equation of a horizontal and a vertical line using standard slope form?
We usually denote the slope of a line as M. Horizontal lines have a slope of zero. Mhorizontal line = 0 Verticle lines have a slope that is undefined. Note that the slope is not infinite, but is undefined. Mvertical line = undefined To write the equation of a horizontal or vertical line, we need to know if it's going to be a slope-intercept form or a point-slope form.
Given the equation of a line how is the slope calculated?
If the equation of a line is in the form ax + by + c = 0 then the slope of the line will be -a/b.
