Graphing Lines slope and y-intercept
Run 3 y-intercept b = -1 Rise 2 slope
Run 2 y-intercept Rise b = 3 -1 slope
Graphing Lines x- and y- intercepts
3x - 2y = 7 find the x value when y = 0 find the y value when x = 0 x-intercept 3x - 2(0) = 7 3x - 0 = 7 3x = 7 find the y value when x = 0 y-intercept 3(0) - 2y = 7 0 - 2y = 7 -2y = 7
The equation 3x +2y = 120 models the number of passengers who can sit in a train car, where x is the number of adults and y is the number of children. Graph the equation.
3x + 2y = 120 find the x value when y = 0 find the y value when x = 0 x-intercept 3x + 2(0) = 120 3x + 0 = 120 3x = 120 find the y value when x = 0 y-intercept 3(0) + 2y = 120 0 + 2y = 120 2y = 120
