What is the equation, in point-slope form, of the line that is parallel to the given line and passes through the point (0,-1)
AfilCa [17]

Answer: in your case, point slope form will be y+1 = (the parellel slope or M)(x-0)

Step-by-step explanation:

basically the point slope form is suppose to be y - (y coodinate) = (M or slope)(x - (x coodinate) )

Parellel lines are the slope is the same, but the coordinates aren't

eg.    what is the equation, in point slope form, of the coordinate of a line (3,4) that is parellel to the equation: y = 3/4x + 6

no. 1: slope is 3/4

no. 2 plug all info into the equation: y - (y coodinate) = (M or slope)(x - (x coodinate) )

no.3 you have your equation! y - 4 = 3 / 4 ( x - 3 )

Which expressions are equivalent to -6+4q+(-6q)
nlexa [21]

Answer:

-2 (q + 3)

Step-by-step explanation:

Simplify the following:

-6 + 4 q - 6 q

Grouping like terms, -6 + 4 q - 6 q = (4 q - 6 q) - 6:

(4 q - 6 q) - 6

4 q - 6 q = -2 q:

-2 q - 6

Factor -2 out of -2 q - 6:

Answer:  -2 (q + 3)
