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.
