Explanation

In the number 62.53, the digit 2 is in the tens place.

The number can be read as: 60 (tens) + 2 (ones) + 0.5 + 0.03

So, place value of 2 = 2 × 10 = 20

Explanation

y = mx + c

This is called the slope-intercept form, where:

 m = slope of the line

 c = y-intercept (value of y when x = 0)

It shows how y changes with x in a straight line.
