Find the product -0.7(-1.1)

0.77

Step-by-step explanation:

-0.7(-1.1) features two negative signs; (-1)^2 = +1, so -0.7(-1.1) must be positive.

Then we have 0.7(1.1).  We can rewrite this with the decimal points moved as follows:  

7(0.1)(11)(0.1)

7 times 11 is 77; 0.1*0.1 = 0.01

Therefore a simpler but equivalent expression is 77(0.01) or 0.77.

the function makes a strait line horizontally with no x intercept but a y intercept at 9.
