Find the equation of a line through two points using slope intercept form.Explore math with our beautiful, free online graphing calculator. Graph functions, plot points, visualize algebraic equations, add sliders, animate graphs, and more.I think the most useful form of straight-line equations is the "slope-intercept" form: y = mx + b y = mx+b. This is called the slope-intercept form because " m " is the slope and " b " gives the y - intercept. (For a review of how this equation is used for graphing, look at slope and graphing .) I like slope-intercept form the best.Note that the expected value is a floating point number, but the actual result is an integer. A quick fix is to change your slope function to: def slope (x1, y1, x2, y2): x2 = (x2 - x1) y2 = (y2 - y1) m = (1.0*y2/x2) return m. Another fix would be to switch to Python 3, or add from __future__ import division to the top of your .py file.

Many schools combine the two topics.The y-intercept of the line. The angle the line makes with respect to the x-axis (measure anti-clockwise). Slope as a percentage ... To find the point where the line crosses the y-axis (i.e., x = 0), enter 12% in percent grade (9, 12) as the coordinate of the first point, and x 2 = 0.As you can see, it is a linear function (the graph is a line) and it crosses the y-axis at the point (0, 3). This tells you that the y-intercept is 3. Since any point along the y-axis has an x-coordinate of 0, the form of any y-intercept is \((0, c)\) for some number \(c\). Using algebra to find the y-intercept of a functionThe y-intercept is at the coordinate that has a 0 for the x-coordinate. X is 0 here and y is -3. X is 0 and y is -3.
