What is the slope of the line represented by the equation y= -1/2x+1/4

stich3 [128]

For this case we have an equation of a line of the form:

$y = mx + b$

Where:

m: It's the slope

b: It is the cutoff point with the y axis

We have the equation:

$y = - \frac {1} {2} x + \frac {1} {4}$

So, we have:

$m = - \frac {1} {2}\\b = \frac {1} {4}$

Answer:

The slope is $- \frac {1} {2}$

Illusion [34]

Answer:

36(5)^-2.

Step-by-step explanation:

5^-2 * 9

= 9(5)^-2

2^4 * 4 ^ -3

= 2^4 + (2^2)^-3

= 2^4 * 2^-6

= 2^-2

So the answer is

9(5^)-2 / 2^-2

= 9(5)^-2 * 2^2

= 4*9(5)^-2

= 36(5)^-2.
