Answer:
Both are proportional, because as the value of x change (increases or decreases), the value of y changes (increases or decreases).
The first equation (y = 25x) could represent that amount of teachers per students. If x = teachers (let's say there is 1 teacher), then y = students (1 teacher would teach a class of 25 students).
The second equation (y = 5x + 25) could represent the amount of money you could earn babysitting. The starting/base amount would be $25, and you would earn $5 more for every hour you babysat.

Answer:
first option;
x-int: -5, 1
y-int: -1
Step-by-step explanation:
<u>x-int:</u> describes where the function touches the x-axis (left to right). This function touches the points (0,-5) and (0,1).
<u>y-int:</u> describes where the function touches the y-axis (up and down). This function touches the point (0,-1).
Answer:
Table 1
Step-by-step explanation:
For a function to be linear, equal changes in x must correspond to equal changes in y.
In all tables, the x values increase by 1, so all changes in x in all 4 tables are 1.
If a function is linear, then all changes in y must be equal.
Table 1:
5 - 6 = -1
4 - 5 = -1
3 - 4 = -1
All changes in y are equal, so the first table is linear.
Table 2:
4 - 3 = 1
6 - 4 = 2
Two differences in y are different, so table 2 is not linear.
Table 3:
6 - 7 = -1
5 - 6 = -1
3 - 5 = -2
Not all differences in y are equal, so table 3 is not linear.
Table 4:
4 - 2 = 2
5 - 4 = 1
Not all differences in y are equal, so table 3 is not linear.
The only table that has equal differences in y corresponding to equal differences in x is Table 1, so only Table 1 shows a linear function.
