It depends on whether or not you have written the question correctly. If the 2 is an exponent, it needs to be preceded by a ^. Otherwise, it is considered a multiplier.
x^2 = x²
x2 = x⋅2

y = x²-1 is nonlinear and nonproportional.

Find the slope of the line that passes through (-34, 81) and (32, 12).
Sauron [17]

Answer:-23/22 or -1.045

Step-by-step explanation:

slope = rise/run

Slope =y2−y1x/2−x1 (The 2's and 1's here should be subscripts sorry)

slope= 12-81 (the y's) divided by 32-(-34)( the x's)

12-81/32-(-34) (Parentehsis just to emphisis the minus a negative number  the second coordinate is -32)

slope= -69/66

simplfy to -23/22 or to decimal

slope = -1.045
