 * Find the equation of the line that goes through the point ( - 6, - 1) and has a slope of 1/3


 * Plug the coordinates of your given point into the slope-intercept equation; then solve for 'b'


 * Find the equation of the line that goes through the points (7,6) and (10,15)


 * First calculate the slope of the line by using the equation: m = **Y2 - Y1 / X2 – X1**


 * The slope of our line is: **3**


 * Once we know the slope we can plug in the coordinates of //one// point that has been given to us into the slope-intercept equation


 * Plug the slope and y-intercept of the equation into the slope-intercept equation to get your final equation
 * **//Final Equation://** **//y = 3x - 15//**
