ON

what is the equation of the line shown:

• y = -3x + 2

• y = -1/3 x + 2

• y = 3x + 2

• y = 1/3 x + 2

Write the equation of the line.

• y = 3x - 2

• y = -3x - 2

Answer explanation

y-intercept is at (0, -2)

Slope is positive

Move up 1 and right 3 OR down -1 and left -3

So the equation is

y = 1/3x - 2

Which is the graph of y=-x+2?

• A

• B

• C

• D

Write the equation of the line.

• y= 3/5x + 1

• y= 3/5x - 1

• y= 5/3x + 1

• y= 5/3x - 1
