Q. The equation of line c is y=−91x−10. Line d includes the point (−9,−7) and is parallel to line c. What is the equation of line d?Write the equation in slope-intercept form. Write the numbers in the equation as simplified proper fractions, improper fractions, or integers.
Determine slope of line c: Determine the slope of line c. The equation of line c is given as y=−91x−10. The slope-intercept form of a line is y=mx+b, where m is the slope and b is the y-intercept. By comparing the given equation with the slope-intercept form, we can see that the slope (m) of line c is −91.
Determine slope of line d: Since line d is parallel to line c, determine the slope of line d. Lines that are parallel have the same slope. Therefore, the slope of line d will be the same as the slope of line c, which is −91.
Use point-slope form: Use the point-slope form to find the equation of line d. The point-slope form of a line is y−y1=m(x−x1), where m is the slope and (x1,y1) is a point on the line. We know that line d passes through the point (−9,−7) and has a slope of −91. Plugging these values into the point-slope form gives us: y−(−7)=−91(x−(−9))
Simplify equation of line d: Simplify the equation of line d.y+7=−91(x+9)y+7=−91x−1Subtract 7 from both sides to get the equation in slope-intercept form:y=−91x−1−7y=−91x−8
