11. Write an equation in point-slope form for the line through the given point with the given slope.

(5,2); m=3

A. y + 2=3(x-5)
B. y + 2= 3x -5
C. y - 2 = 3 (x+5)
D. y - 2=3(x-5)

12. (-3,-5); m= - 2/5

A. y + 5= - 2/5 (x+3)
B. y + 5= (- 2/5) x-3
C. y - 5= - 2/5 (x+3)
D. y - 5= - 2/5 (x-3)

13. (5, -6); m= -0.38

A. y+6 = -0.38 (x+5)
B. y-6 = -0.38 x-5
C. y-6 = -0.38(x+5)
D. y+6 = -0.38 (x-5)

Write y= (- 5/8) x +3 in standard form using integers.

Write y= - 2/3 x+2 in standard form using integers.

Write an equation for the line that is parallel to the given line and passes through the given point.

y= 2x +4; (3,8)

A. y= 2x +2
B. y= 2x +6
C. y= -2x +6
D. y= - 1/2 x+2

Tell what the lines are

y = -3x +7

-2x +6y =3

A. parallel
B. perpendicular
C. neither
