How do you verify if a point is a solution to the system of equations?

• By calculating the slope only

• By checking if the point satisfies at least one equation

• By graphing the point only

• By checking if the point satisfies all equations

What is the first step in solving systems of equations graphically?

• Find the y-intercept

• Convert all equations to slope-intercept form

• Graph both lines in the same coordinate plane

• Identify the slope
