Example: What is the equation of this line? Start with the "point-slope" formula: y − y1 = m(x − x1) Put in these values: x1 = 1 y1 = 6 m = (2−6)/(3−1) = −4/2 = −2 And we get: y − 6 = −2(x − 1) Simplify to Slope-Intercept (y = mx...

Equation from 2 points using Point Slope Form As explained at the top,point slope formis the easier way to go. Instead of 5 steps, you can find the line's equation in 3 steps, 2 of which are very easy and require nothing more than substitution! In fact, the only calculation, that ...
two-point form TheY-interceptof a line is the point of intersection of the Y-axis and the line (if any). This point may not exist (in the case the line is parallel to theYaxis), or there may be infinitely many intersection points. ...
Problem: Find the equation of a line in the slope-intercept form given points (-1, 1) and (2, 4) Solution: Calculate the slopea: Calculate the interceptbusing coordinates of either point. Here we use the coordinates (-1, 1):
The equation of the line can be written in many forms. One of which is the standard form. Almost every type of graph has its standard equation. In the case of a line, the standard form is written in the formAx+By=C. Note that the other forms can also be derived...
you're learning about linear equations, you're bound to run into the point-slope form of a line. This form is quite useful in creating an equation of a line if you're given the slope and a point on the line. Watch this tutorial, and learn about the point-slope form ...
