Let the equation of the straight line l be (m-2m-3) x - (2m + m-1) y = 2m-6, and determine the value of the real number m according to the following conditions: (1) the intercept on the X axis is - 3; (2) the slope is - 1

Let the equation of the straight line l be (m-2m-3) x - (2m + m-1) y = 2m-6, and determine the value of the real number m according to the following conditions: (1) the intercept on the X axis is - 3; (2) the slope is - 1

(1) Y = 0, the intercept is (2m-6) / (m-2m-3) = - 3, finishing 3m-4m-15 = 0, (3m + 5) (M-3) = 0, M = 3 (rounding off) or - 5 / 3. M = - 5 / 3 (2) the slope is (m-2m-3) / (2m + m-1) = - 1, 3m-m-4 = 0, (3m-4) (M + 1) = 0, M = - 1 (rounding off) or 4 / 3. M = 4 / 3
