  3] 4x -3y = 3

  4] x -2y = -2

  5] y = 3; x = -1

Step-by-step explanation:

3] The standard form equation can start with the form ...

  (y2 -y1)(x -x1) -(x2 -x1)(y -y1) = 0

  (-9 -(-1))(x -0) -(-6 -0)(y -(-1)) = 0

  -8x +6(y +1) = 0

In standard form, we want the leading coefficient to be positive, and we want the constant to be on the right side of the equal sign. We also want the coefficients to be mutually prime (all common factors removed). So, dividing the equation by -2 gives ...

  4x -3(y +1) = 0

  4x -3y -3 = 0

  4x -3y = 3 . . . . standard form equation

4] Same deal, different points.

  (6 -(-5))(x -(-12)) -(10 -(-12))(y -(-5)) = 0

  11(x +12) -22(y +5) = 0

  x -2y = -2 . . . . simplify to standard form

5] A horizontal line has the equation y = constant. A vertical line has the equation x = constant. To make these lines go through the given point, the constants need to be equal to the corresponding coordinates:

  y = 3

  x = -1

a. turk and mcalister

b. howard, mission, and market

c. yes. since streets end some do not cross yet are not parallel to others. example: mcalister and 5th

step-by-step explanation:

parallel lines are lines which do not intersect ever and look a lot like railroad tracks. turk, mcalister and golden gate are examples of these.

intersect are streets which cross each other and a car on one can reach the other. howard, mission, and market intersect with 6th.

skew lines are lines which neither intersect nor are parallel. these lines exist here because some streets end and never intersect another like mcalister and 5th.
