If the vertical distance from the ground to the door bottom is 2.5 ft, find the distance the ramp has to extend from the home in order to comply with the needed slope. 1 We see that the slope is 3 4 3 6 First, we will write the equation in slope-intercept form to find the slope. Click this link and get your first session free! We do this because when the equation is multiplied by the LCD, the common factors in the LCD and in each denominator will equal one and will cancel out. 2x 32 The product of the first two denominators is equal to the third denominator, so, the LCD is 3 ) . 2, q A rational equation contains at least one rational expression where the variable appears in at least one of the denominators. 8. . 12 x2 To write the equation of a line parallel or perpendicular to another line, we follow the same principles as we do for finding the equation of any line.
