Find the slope from the table:
X | Y
0 | -1
2 | 3
5 | 9
6 | 11

The slope is 2

Step-by-step explanation:

Pick two points.

ex: (0,-1) and (2,3)

do the equation below where 0=x1, -1=y1, 2=x2, 3=y2

y2-y1 divided by x2-x1

3-(-1) divided by 2-0

4/2

=2

sorry this was kind of hard to explain on a computer :/

24 and 21 are the two numbers

Step-by-step explanation:

let n represent the unknown number

let n-3 represent the second unknown number

n+n-3 = 45

2n-3=45

2n=45+3

2n=48

n=48/2

n=24

n-3=21

CHECK: 24+21=45

.˙. the first number is 24 and the second number with a difference of 3 is 21
