• Cannot be Determined

How would you write the equation of a line with a slope of 2/3 and a y-intercept of -3?

• y=(3/2)x+3

• y=(2/3)-3

• y=(2/3)x-3

• y=(2/3)x+3

Which equation best represents the line on the graph?

• y= (1/2)x

• y= (-1/2)x

• y = 2x

• y = -2x

What is the equation of the line?

• y = (-3/4)x + 3
