Graphing Linear Equations with X & Y Intercepts

What is the x-intercept of a line?

• The point where the line intersects the origin

• The point where the line crosses the y-axis

• The point where the line crosses the x-axis

• The point where the line is parallel to the x-axis

How do you find the x-intercept of the equation 2x + 3y = 6?

• Set both x and y to 0

• Plug in 0 for y and solve for x

• Plug in 0 for x and solve for y

• Divide the equation by 2
