What do you think?
i can't think of anything when i have 3 days left and 2 exams left
1. Eq1: Y = 6x + 2.
Eq2: - 18x + 3y = 12.
m1 = 6.
m2 = -A/B = 18/3 = 6.
The Eqs have equal slopes and are, therefore, parallel and do not intersect:
No solution.
2. Same procedure as #1.
3. Standard Form: -5x + y = -6, and -15x + 3y = -12.
Same procedure as #1.
Eq2: - 18x + 3y = 12.
m1 = 6.
m2 = -A/B = 18/3 = 6.
The Eqs have equal slopes and are, therefore, parallel and do not intersect:
No solution.
2. Same procedure as #1.
3. Standard Form: -5x + y = -6, and -15x + 3y = -12.
Same procedure as #1.
2. Multiply the 1st Eq by 3 and you'll notice that the Eqs are identical and have infinite solutions.
Bro i have 3 days and all my exams left ðŸ˜ðŸ˜ðŸ˜
