WebSolution: Given equations are y = -3x + 9 y = -3x – 7 Here (a 1 /a 2) = (b 1 /b 2) ≠ (c 1 /c 2 ). So this system of equations has no solution. Another method: Without graphing them, we can see that both have the same slope -3 which means lines are parallel. Hence the system of equations has no solution. So option (B) is the answer. Example 2: WebExample. Our goal is to find the number of solutions to this quadratic equation: 9 x 2 + 42 x + 49 = 0. Our first order of business is to identify the coefficients a, b, and c (this helps us calculate the discriminant): a = 9, b = 42, c = 49. We’ve identified the coefficients, so we can evaluate the discriminant by substituting these ...
