Find the coordinates of the x- and y-intercepts for this equation:

2x + y = 6

1) Substitute in a ZERO for y and find the x-value or x-intercept.

2) Substitute in a ZERO for x and find the y-value or y-intercept.

The answers list the coordinate for the X-intercept first and then the coordinate for the Y-intercept.

(x, 0) and (0, y)

• (0, 3) and (6, 0)

• (0, -3) and (-6, 0)

• (3, 0) and (0, 6)

• (-3, 0) and (0, -6)

Which ordered pair could represent a y-intercept on a graph?

HINT: If you are looking for a Y-Intercept the "other" variable is equal to zero.

• (6, 0)

• (0, 4)

• (-1, 3)

• (2, 0)

_{What is the y-intercept of the line?}

•  (0,¹/₂)
• (0,1)
• (0, ^-1/2)
• (0, -1)

^{What is the x- intercept of the line?}

• (1, 0)

• (2, 0)

• ( -1, 0)

• (-2, 0)

Find the y-intercept for 3x + y = 5.

REMEMBER: When looking for the y-intercept substitute a zero in for the "other" variable.

• -3

• 5

• -5

• 3
