What is the formula for Slope-Intercept Form of the Line

Answers

It's not the slope-intercept form of the line. 

It's the slope-intercept form of the line's equation.

                   Y = mX + B

'X' is the slope of the line

'B' is the y-intercept of the line
The formula would be : m = [y1 - y2] / [x1 - x2]

Explain why 90 is not a square number

Answers

90 is not a square number because you cannot multiple two of the same number to get 90.

For example, 4 is a square number, because 2 x2 = 4

Likewise, 9 is a square number (3 x3), and 81 is a square number (9 x 9)
