M=-1/4 what is the parallel slope and the perpendicular slope?

Parallel slope = -1/4 and perpendicular slope = 4.

Step-by-step explanation:

If an equation of a line y = mx +c is given then it's gradient ( slope) is m.

then the slope parallel to this line will be equal to the slope of the original line that is equal to m.

We know for two lines perpendicular to each other formula is

m × m' = -1 or

Now for m = -1/4

Slope of parallel line slope will be = -1/4

and slope of perpendicular line

So the answer is (-1/4) and 4.

step-by-step explanation:

a

(6r + 7) + (13 + 7r) ( remove brackets and collect like terms )

= 6r + 7 + 13 + 7r

= 13r + 20

b

remove brackets and collect like terms

13 - r - 1 + r

= 12 - r

c

remove brackets and collect like terms

= - 8 - r + 2r - 4

= - 12 + r

d

remove brackets and collect like terms

= 7r - - - 6r

[-   - = - - = - ]

= r -
