So y=mx+b form
m=slope=rise over run
b=y intercepe or where it crosses the y axis
so one way is to input values for x and get vales for y exg
if x=1 then y=-2
if x=2 then y=1
if x=0 then y=-5 so some points are
(x,y)
(1,2)
(2,1)
(0,-5)
(3,4)
then plot those points
Answer:
Part 1 = $1.32
Step-by-step explanation:
.72 divided by 6 is 12. So they make 12 cents per ticket, so that means you would have to do 12 times 11 and that should get you 132 cents and that is equivalent to $1.32.
Answer: 13
Step-by-step explanation: In this problem we're asked to rewrite as addition and then evaluate.
It's important to understand that minus a negative means the same thing as plus a positive so we can change 5 - (-8) to 5 + (+8).
Now we can simply add to get a sum of 13.
Therefore, 5 - (-8) or 5 + (+8) = 13
Answer:
The relationship is linear, and of the form:
(last option in the list of possible answers)
Step-by-step explanation:
Yes, the relationship is linear. Such can be clear by examining if the rate of change when using different pairs of x,y coordinates. Notice for example that when you do the difference between consecutive y-values of the table, you always get "5":
10-5 = 5
15-10 = 5
20-15 = 5
and the respective differences between consecutive x-values of the table, always render "4":
5-1 = 4
9-5 = 4
13-9 = 4
This tells us that the associated rates of change are constant and equal to "5/4".
This is then the slope of the line that joints all of those points.
Now, in order to find a point-slope form for this line one can use the first pair (1, 5) for the point we want the line to go through, and apply the general slope-point for a line knowing that the slope m = 5/4, and that we can use the point (1, 5) as the particular point to define it:
, which is in fact the last option given in the choice of answers.
