Learn how to solve a system of equations by graphing Solution

The video tutorial explains how to solve an equation for Y by isolating it, then graphing the equation to find the slope and Y-intercept. The instructor demonstrates plotting points on a graph and finding the intersection point, emphasizing the importance of accuracy in graphing. The tutorial concludes with an estimation of the intersection point due to graph imperfections.

What is the result of dividing the equation by -3?

• Y = 1/3X - 1/3

• Y = -1/3X + 1/3

• Y = 3X - 1

• Y = -3X + 1

What is the slope of the equation Y = -1/3X + 1/3?

• -3

• 3

• 1/3

• -1/3

When graphing the equation, what is the first point you should plot?

• (1, 0)

• (0, 1/3)

• (3, 0)

• (0, 3)

How do you determine the next points to plot after the Y-intercept?

• Go up 1 and right 3

• Go down 1 and right 3

• Go down 1 and right 1

• Go up 1 and left 3

What is the estimated intersection point of the two lines?

• (2, 1)

• (3, 0)

• (4, -1)

• (5, -2)
