Q. How many solutions does the system of equations below have?y=7x−72y=85x−76Choices:(A)no solution(B)one solution(C)infinitely many solutions
Analyze Slopes: Analyze the slopes of the two equations.The slope of the first equation y=7x−72 is 7.The slope of the second equation y=85x−76 is 85.Since the slopes are different, the lines are not parallel.
Unique Solution: Since the slopes are different, the lines will intersect at exactly one point. This means there is one unique solution to the system of equations.
No Y-intercept Check: There is no need to check the y-intercepts because the slopes are different, which guarantees that the lines will intersect at some point.
