Q. The equation for line g g can be written as y+6=74(x6) y+6=-\frac{7}{4}(x-6) . Line h h is parallel to line g g and passes through (6,7) (6,-7) . What is the equation of line h h ?\newlineWrite the equation in slope-intercept form. Write the numbers in the equation as simplified proper fractions, improper fractions, or integers.
  1. Understand Relationship: Understand the relationship between lines gg and hh. Since line hh is parallel to line gg, they will have the same slope.
  2. Find Slope of Line g: Find the slope of line g. The equation of line g is given in point-slope form: y+6=74(x6)y + 6 = -\frac{7}{4}(x - 6). The slope of line g is the coefficient of xx, which is 74-\frac{7}{4}.
  3. Use Slope for Line h: Use the slope of line g for line h.\newlineSince line h is parallel to line g, the slope of line h is also 74-\frac{7}{4}.
  4. Find y-Intercept of Line h: Use the point (6,7)(6, -7) to find the y-intercept of line h.\newlineWe will use the slope-intercept form y=mx+by = mx + b, where mm is the slope and bb is the y-intercept.\newlinePlug in the slope 74-\frac{7}{4} and the point (6,7)(6, -7) into the equation to solve for bb.\newline7=74(6)+b-7 = -\frac{7}{4}(6) + b\newline7=424+b-7 = -\frac{42}{4} + b\newline7=212+b-7 = -\frac{21}{2} + b\newlineTo find bb, add y=mx+by = mx + b11 to both sides of the equation.\newliney=mx+by = mx + b22\newliney=mx+by = mx + b33\newliney=mx+by = mx + b44
  5. Write Equation of Line h: Write the equation of line h in slope-intercept form.\newlineNow that we have the slope (74)\left(-\frac{7}{4}\right) and the y-intercept (72)\left(\frac{7}{2}\right), we can write the equation of line h.\newliney=74x+72y = -\frac{7}{4}x + \frac{7}{2}\newlineTo simplify the y-intercept to match the requested format, we convert 72\frac{7}{2} to quarters.\newline72=144\frac{7}{2} = \frac{14}{4}\newlineSo the y-intercept in quarters is 144\frac{14}{4}, but we need to subtract 74x\frac{7}{4}x from both sides to get the y-intercept alone.\newline14474=74\frac{14}{4} - \frac{7}{4} = \frac{7}{4}\newlineTherefore, the y-intercept is 74\frac{7}{4}, and the equation of line h is:\newliney=74x+74y = -\frac{7}{4}x + \frac{7}{4}\newlineHowever, we made a mistake in the calculation of the y-intercept. Let's correct it:\newline(72)\left(\frac{7}{2}\right)00\newline(72)\left(\frac{7}{2}\right)11\newlineConverting to quarters:\newline(72)\left(\frac{7}{2}\right)22\newlineSo the correct y-intercept is 144\frac{14}{4}, which simplifies to 72\frac{7}{2}.\newlineThe correct equation of line h is:\newliney=74x+72y = -\frac{7}{4}x + \frac{7}{2}\newlineBut we need to express the y-intercept as an improper fraction or integer. Since 72\frac{7}{2} is already in simplest form, we leave it as is.\newlineThe final equation of line h is:\newliney=74x+72y = -\frac{7}{4}x + \frac{7}{2}
