Answer:
The equation of the line that goes through points (1,1) and (3,7) is 
Step-by-step explanation:
Determine the equation of the line that goes through points (1,1) and (3,7)
We can write the equation of line in slope-intercept form
where m is slope and b is y-intercept.
We need to find slope and y-intercept.
Finding Slope
Slope can be found using formula: 
We have 
Putting values and finding slope

We get Slope = 3
Finding y-intercept
y-intercept can be found using point (1,1) and slope m = 3

We get y-intercept b = -2
So, equation of line having slope m=3 and y-intercept b = -2 is:

The equation of the line that goes through points (1,1) and (3,7) is 
Answer:
Its asking you which one is greater or less than. Hope this help?
Step-by-step explanation:
$8.25
The first 5 checks are free so you can subtract the 5 from 18 which is 13. Then you multiply 13 & .25 which is equal to $3.25 and then you just add the $5
Answer:

Step-by-step explanation:
We are told that the average human heart beats
times per day and there are
days in one year.
To find number of heart beats in one year we will multiply number of heart beats in one day by number of days in one year.

Now we will solve this problem using exponent properties.



Our answer is in scientific notation we can represent it in standard form as
times.
Therefore, average human heart beats in one year
or 41975000 times.
