We write the equation in the directional form.and -1 = 6x ⇔ y = 6x + 1y - 1 = 3x ⇔ y = 3x + 1 - 7 = 2x - 6 ⇔ y = 2x - 6 + 7 y = 2x + 1y - 7 = x - 2 ⇔ y = x - 2 + 7 y = x + 5Equations skillfully laid out .The point Q = (0,1) b factor , not only adapts the last equationIn the drawing have recorded the points Q and R are tangent to the linear function corresponding to that point . This graphics solution . y = 3x + 1Answer bWe verification option for the system of equations , where a substitute wartoćsi points Q and R for the model of linear equations functionThe result of equations confirmed our choice Response bFigure I'm going to add soon
