The line y = mx + c has a slope of m.
Parallel line:
A parallel line will also have a slope of m, and should be of the form
y = mx + k
Because the line passes through the point (a,b), therefore
ma + k = b
k = b - ma
The equation of a parallel line is
y = mx + b - ma
= m(x-a) + b
Perpendicular line:
A perpendicular line will have a slope of -1/m, because the product of slopes should be -1.
The equation for a perpendicular line is of the form
y = -(1/m)x + k
Because the line passes through (a,b), therefore
-(1/m)a + k = b
k = b + a/m
The equation for a perpendicular line is
y = -(x/m) + b + a/m
= -(1/m)(x-a) + b
Answer:
Parallel line:
Perpendicular line:
So we can do this by finding how much is needed for one pancake first.
50ml of milk is needed to make 1 pancake.
From there we can multiply it by 6 to figure out how much we need for 6.
Alternatively, you can just divide 400 by 8/6 but some people find that confusing and it's often easier to follow workings if you do the above method.
300ml of milk is needed to make 6 pankakes.
