- Point-Slope Form is helpful when you know one point on the line and the slope. Standard Form is useful for finding intercepts and when both x and y variables are important.

The point slope form, (y-y 1) = m (x-x 1), is useful in situations involving slope and the location of one or more points. The standard form, A x + B y = C , is usually easier to use when we need to make algebraic calculations.
Jan 26, 2020 · Slope Intercept Form: $y = (\text{slope})x + (\text{$y$-intercept})$ Significance: As the name suggests, one can write a line in this form to directly compare to get slope and the y-intercept. One Point Slope form: $(y-y_1) = (\text{slope})(x-x_1)$ where $(x_1,y_1)$ is a point on the line. Two Point form: Just replace slope from above equation ...
Point-Slope Equation of a Line. The "point-slope" form of the equation of a straight line is: y − y 1 = m (x − x 1) The equation is useful when we know: one point on the line: (x1, y1) and the slope of the line: m, and want to find other points on the line.

Recall that a linear equation is a mathematical equation that defines a line. While each linear equation corresponds to exactly one line, each line corresponds to infinitely many equations. These equations will have a variable whose highest power is 1. The three main forms of an equation are slope-intercept form, point-slope form, and standard form...
As the name implies, point-slope form gives one point in a line and its slope. This form is not commonly given to help graph a line. It is, however, more commonly used to get from a verbal description or a graphical depiction of a line to slope-intercept or standard form. If the given point is (x1, y1), a the slope is m, the equation of the line in...
Slope-intercept form conveys the slope and y-intercept of a line. It is actually technically a special case of point-slope form. If a line has slope m and y-intercept (0, b), the slope-intercept form is: y=mx+b. If this point was written in point-slope form, we would have: y-b=m(x-0). Simplifying yields: y=mx-0+b y=mx+b. If the graph of the line is...
The standard form of an equation is: Ax+By=C Where A, B, and C are all whole numbers, and A is not negative. This form is useful in two ways. Namely, it helps us to solve a system of equations and it helps us to find the intercepts of the equation.
The Point Slope Form for finding the equation of line is given by (y – y 1) = m ((x – x 1) where, (x, y) is just a random point on the line; (x 1, y 1) is a fixed point given on the line and m is the slope of the line.
We use point-slope form when we know a point \( (x_1, y_1) \) on the line, and the slope \(m\). Given this information, the equation of the line is \[ ( y - y_1) = m ( x - x_1).
