CCSS.8.F.A.3

• slope = -3

  y-int. = (0, -2)

• slope = 3

  y-int. = (0, -2)

Answer explanation

The slope is the number (or fraction in front of x) and the y-intercept is the constant number being added (or subtracted) at the end.

• slope = 1

  y-int. = (0, 3)

• slope = -1

  y-int. = (0, 3)

• slope = 3

  y-int. = (0, 1)

• slope = 3

  y-int. = (0, -1)

Answer explanation

The slope is the number (or fraction in front of x) and the y-intercept is the constant number being added (or subtracted) at the end.

• slope = -1

  y-int. = (0, -3)

• slope = -1

  y-int. = (0, 3)

Answer explanation

Solve for y.

The slope is the number (or fraction in front of x) and the y-intercept is the constant number being added (or subtracted) at the end.

• slope = -2

  y-int. = (0, 10)

Answer explanation

Solve for y.

The slope is the number (or fraction in front of x) and the y-intercept is the constant number being added (or subtracted) at the end.
