What is the slope of the line graph below?
a)-1/2
b)1/2
c)1
d)2

D) 2

Step-by-step explanation:

If we look at the graph we can see that it has the points :

(0,1) and (1,3)

Since it's a linear equation the slope is the same throughout the graph so we can evaluate the slope from these 2 points.

The formula fro calculating slope is rise/run

In other words,

Where x1 = 0, x2 = 1, y1 = 1, y2 = 3

So slope  =

So the answer is 2

-13

step-by-step explanation:

f(x)=2x-5 for f(-4)

f(-4)   means let x=-4

f(-4) = 2(-4) -5

f(-4) =-8-5

      = -13

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
