Hm; Slope? dunno how 2 do this??

Question

35) What is the slope of the line containing the points (–7, 3) and (2, 5)?

33) A graph of a relation is shown below. Refer to the graph to answer the following questions: (a) State each point of the relation as a set of ordered pairs. (b) What is the domain of the relation? (c) What is the range of the relation? (d) Is the relation a function? Explain. Note: Each square of the grid is one unit in length

[[look at graph thingy??]]

Answer 1

the slope is equal to the change in y over the change in x. The slope can be represented by "m"

therefore, the formula is:

m=Y2-Y1/X2-X1  *2 and 1 are subscripts

m=5-3/2-(-7)

m=2/9

Answer 2

35) What is the slope of the line containing the points (–7, 3) & (2, 5)?

5-3 over 2 - -7

2/9

a) (-2,0)

(-2,-2)

(0,1)

(3,0)

(3,2)

b) D={-2,1,3}

------------------------------

R={-2,0,1,2}

not a function. In a function for every value in the domain (x value) there is only one value in the range (y value) In this you have two y values when x is -2 and when x is 3
