(16/25)-3/2 help me solve​

Answers

Answer:

-43/50

(decimal) = -0.86

Step-by-step explanation:

Find the LCD which is 50.

16/25 will be multiplied by 2 (because 25 x 2 = 50) so it will then equal 32/50

3/2 will be multiplied by 25 (2 x 25 = 50) = 75/50

subtract them which will give you -43/50

What is the slope of this line?

Answers

Answer:

A line is increasing if it goes up from left to right. The slope is positive, i.e. m > 0 {\displaystyle m>0} .

A line is decreasing if it goes down from left to right. The slope is negative, i.e. m < 0 {\displaystyle m<0} .

If a line is horizontal the slope is zero. This is a constant function.

If a line is vertical the slope is undefined (see below).
