Aline is represented by the equation x + 2y=4. what is the slope of the line with that equation?

The slope is -1/2

Step-by-step explanation:

x + 2y=4

Lets get the equation in the form y= mx+b

where m is the slope and b is the y intercept.

x + 2y=4

Subtract x from each side

x-x+2y = -x+4

2y = -x+4

Divide each side by 2

2y/2 = -1/2 x +4/2

y = -1/2x +2

The slope is -1/2

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!
