[tex]y = mx + c[/tex] Where m is the slope, given by;
[tex]m = \frac{5 - - 10}{6 - 3} [/tex] [tex]m = \frac{5 + 10}{6 - 3} [/tex] [tex]m = \frac{15}{3} = 5[/tex] We substitute the value of m into the equation to obtain;
[tex]y = 5x + c[/tex] We find c by substituting any of the points,
[tex]5= 5(6) + c[/tex] [tex]5 = 30 + c[/tex] [tex]c = - 25[/tex] This implies the equation in slope intercept form is;
