2x+8y=4 what is the slope of a line parallel to this line? what is the slope of a line perpendicular to this line?

see explanation

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Rearrange 2x + 8y = 4 into this form

Subtract 2x from both sides

8y = - 2x + 4 ( divide all terms by 8 )

y = - x + ← in slope- intercept form

with slope m = -

• Parallel lines have equal slopes, thus

slope of parallel line = -

Given a line with slope m then the slope of a line perpendicular to it is

= - = - = 4

-362

step-by-step explanation:

(12)(4)+2(12)-34(12)+2(12)-3

  \/         \/         \/         \/

  48 +   24 -   408 + 24 - 3

      \   /               \   /

          72     -     432 - 3 = -363

the answer would be d

straight away you can eliminate a and c because not all books contain a scientific skill because some may be fiction. c is also wrong because it saids that the only way children can learn is through books which is incorrect.

b is also wrong because reading can be a scientific skill but not always, therefore it is wrong which leaves you with d, the correct answer since it said that it can children learn.

hope this ! : 3
