Question 30 • Mathematics I
The first equation is already in slope-intercept form: y = (1/3)x − 4, so its slope is 1/3. Rearranging 3y − x = −7 gives y = (1/3)x − 7/3, which has the same slope but a different y-intercept. The lines are parallel, so both “Both lines have the same slope” and “The system consists of parallel lines” are true.
