Parallel lines have the same slope and different y-intercepts. ), parallel to x n d + The slope of a vertical line is undefined, and regardless of the y-value of any point on the line, the x-coordinate of the point will be c. Suppose that we want to find the equation of a line containing the following points: ) and When the variable is multiplied by a coefficient in the final stage, multiply both sides of the equation by the reciprocal of the coefficient. , 1, then you must include on every physical page the following attribution: If you are redistributing all or part of this book in a digital format, = w The proposed solution is 1, 2-7 Practice ANSWERS. 3, x See Figure 3. ), ( 1,3 2x x2 = Next, we use the point-slope formula with the slope of 19 30 b = 1. , x3 4 7x5y=25. Thus, the LCD that contains each denominator is , = x ( which results in x1 2. x -intercept is (4, 0); y- intercept is (0, 3). = x 2 +2x. On the y-axis, , 2y=x+4. . If done correctly, the same final equation will be obtained. , 2 Here are three examples.
