Question

Algebra 1 9th grade help please!!!!
Part 1: Provide a system of TWO equations in slope-intercept form, with only one solution. Using complete sentences, explain why this system has one solution.

Part 2: Provide a system of TWO equations in slope-intercept form with no solutions. Using complete sentences, explain why this system has no solutions.

Part 3: Provide a system of TWO equations in slope-intercept form with infinitely many solutions. Using complete sentences, explain why this system has infinitely many solutions.

Answer 1

Part 1: one solution. This would mean you have 2 lines that intersect (meet). the point where they meet is the solution.

Can you write down the equation of a line ? and a different line that crosses the first line ?

Answer 2

No solution means the lines never meet. That means the lines are parallel. Can you write the equations of 2 lines that have the same slope (meaning they are parallel) but different y-intercepts
