Q. Which equation represents a line which is parallel to the line 7y−x=−56 ?Answery=−71x+7y=71x−1y=7x−4y=−7x−2
Find Slope: First, find the slope of the given line 7y−x=−56. Rewrite in slope-intercept form(y=mx+b). 7y=x−56y=71x−8 Slope (m)=71
Identify Parallel Line:Parallel lines have the same slope. So, the slope of the parallel line is also 71.
Check Options: Check the given options for the same slope. y=−71x+7 (Slope = −71, not parallel) y=71x−1 (Slope = 71, parallel) y=7x−4 (Slope = 7, not parallel) y=−7x−2 (Slope = −7, not parallel)
Final Equation: The equation y=71x−1 has the same slope as the given line.
