Describe the pattern in the table using an equation:
x|y
1|15
2|25
3|35
4|45
When x increases by 1, y increases by 10.
To describe the pattern in the table using an equation, we need to look for a relationship between the values in the x-column and the values in the y-column.
In this table, we can observe that the value in the y-column is always 10 more than 10 times the value in the x-column.
So, we can write the equation as:
y = 10x + 10
This means that for any given value of x, the corresponding value of y can be found by multiplying x by 10, and then adding 10 to the result.
For example, if we substitute x = 2 into the equation, we get:
y = 10(2) + 10
y = 20 + 10
y = 30
Similarly, if we substitute x = 4 into the equation, we get:
y = 10(4) + 10
y = 40 + 10
y = 50
Therefore, the equation y = 10x + 10 describes the pattern in the table.
