What is the slope-intercept form of the equation 2x + y = 4?
Goryan [66]
<h3>Answer:</h3>

slope intercept form:  y = -2x + 4

<h3>Explanation:</h3>

\sf slope \ intercept \ form: y = mx + b

where m is slope, b is y-intercept

=============================

\rightarrow \sf 2x + y = 4

\rightarrow \sf  y = 4-2x

\rightarrow \sf  y = -2x +4

Now, identify slope: -2, y-intercept: 4

Answer: The midpoint of segment PQ is the number 2.5

note: 2.5 as a fraction is 5/2; as a mixed number 2.5 converts to 2&1/2

============================================================

Explanation:

Apply the midpoint formula to get the midpoint of -8 and 6

We simply add up the values and divide by 2 and we get (-8+6)/2 = -2/2 = -1

So point Q is at -1 on the number line, which is exactly halfway from R to P

Focus on just points P and Q now. Apply the midpoint formula again

Q = -1

P = 6

(Q+P)/2 = (-1+6)/2 = 5/2 = 2.5

So the midpoint of segment PQ is 2.5

The decimal 2.5 can be written as the mixed number 2&1/2, showing that this new point is exactly halfway between 2 and 3.
