Point-slope form is written as:

y-y1=m(x-x1), where (x1, y1) is a point on the line and m is the slope (hence the name, point-slope form).

1. Slope-intercept form (most commonly used in graphing) y=mx+b m=slope b=y-intercept 2. Standard form ax+by=c 3. Point slope form (most commonly used for finding linear equations) y-y1=m(x-x1) m=slope one point on the graph must be (x1,y1)

It does not matter because they are equivalent. You can always convert from a slope-intercept form to a standard linear form (and vice versa).

slope intercept form, rise over run

Equations are not linear when they are quadratic equations which are graphed in the form of a parabola

That's because lines, or curves, can have different slopes.

Because a linear equation is, by definition, a straight line. Any line can be defined by selecting any one point on the line and the slope of the line.

Point-slope form is just another way to express a linear equation. It uses two (any two points that fall on the line) and the slope of the line (Therefore the name point-slope form).y2 - y1 = m(x2 - x1)...with m as the slope.

The slope-intercept form of the equation is y = mx + b, where m represents the slope and b represents the y-intercept. It is used to graph linear equations easily.

It depends on what constitutes different looking: how similar must the equations be before you see that they are the same. If both equations are in the point-slope form, the coefficients of one equation must be a fixed multiple of the coefficients of the other.

Standard form: Ax + By = C, where A and B are non-zero constants. Slope-intercept form: y = mx + b, where m is the slope, and b is the y-intercept.
