1.) Write the equation for the line in slopeintercept form:Slope: m=3; Yintercept: B=7
*y  3 = 7(x  3)
*y = 3x + 7
*y = 7x  3
2.)Write the equation for the line in slopeintercept form: Slope: m=4/3; Yintercept: b=2
*y = 4/3x  2
*y + x = 2x + 1/2
*y = 1/2x  2
3.)Which of the following lines is perpendicular to the line x + y = 3?
*3y + 3x = 1
*y = x + 1/2
*y = x + 3

1) y= 3x + 7
2) y= 4/3x  2
3) y= x + 1/2
