Q. How many solutions does the system of equations below have?y=−7x+9y=79x−47Choices:(A)no solution(B)one solution(C)infinitely many solutions
Analyze slopes: Analyze the slopes of both equations.Equation 1: y=−7x+9, slope = −7.Equation 2: y=79x−47, slope = 79.Check if slopes are equal or different.
Check slopes: Since the slopes are different (−7=79), the lines are not parallel and will intersect at one point.Determine the number of solutions when lines intersect.
