Key Point The equation of a straight line with gradient m and intercept c on the y-axis is y = mx+c. An equation ends at a newline character. The equation of a straight line is usually taught in the form: y = mx + c. which succinctly expresses the fact that if we plot y against x and the variables obey a relationship of this form we will obtain a straight line graph with gradient or slope m and intercept (where the line crosses the y-axis) c (fig 1) . This defines a function.The graph of this function is a line with slope − and y-intercept −. Find an equation of the line that passes through C and is perpendicular to AB. This number c is called the intercepton the y-axis. The elements of S correspond to axioms and the group … A straight line is defined by a linear equation whose general form is.
