The slope of a line is how steep the graph of the line is, or the rate of change of the y-coordinates of the points of the graph as you go from left to right. In the equation of a line, slope is denoted by m. It’s not known why m is used, but you can think “m is for move” to help you remember it’s how fast the graph “moves” (changes).
Read MoreYou have two options for writing the equation of a line: point-slope form and slope-intercept form. Both of them require that you know at least two of the following pieces of information about the line: 1) a point, 2) another point, 3) the slope, m, or 4) the y-intercept, b (the y-coordinate of the point at which the graph of the line crosses the y-axis).
Read MoreA linear equation is the equation of a line. When you graph a linear equation, it’s best to write the equation in slope-intercept form: y=mx+b. Remember that m is the slope of the line and b is the y-intercept (the y-coordinate of the point at which the line crosses the y-axis).
