Answer:
=the quantity of 3x plus 5 divided by 2
Step-by-step explanation:
We are given that a function 
We have to find the correct expression
Suppose y=
Therefore, 
Answer:=the quantity of 3x plus 5 divided by 2
The first thing to do with these problems is to convert them into y=mx+b form; this will literally show you the answer to slope and y intercept since m=slope and b=y intercept.
To convert, isolate the y and the rest should fall into place. Subtract 2x from 4y and the other side of the equation to get the equation 4y= -2x+9 (put the x first because of mx+b). Then Divide the 4 from y and do the same to the other side to get y= -1/2x+9/4. M= -1/2 so that is the slope. B=9/4 so that is the y intercept
Answer:
in bold
Step-by-step explanation:
M is the slope and b is the y intercept
1 looks correct
2. Chose 2 points; I chose (0,2) and (2,2) Find slope: 0/-2=0 y=mx+b y=0x+b y=b b=2 y=2
3. Chose 2 points: I chose (2,9) and (0,5) Find slope: 4/2=2 y=mx+b y=2x+5
4. Chose 2 points: I chose (0,-2) and (2,-3) Find slope: 0--3/-2-2=3/-4 y=mx+b y=-3/4x-2
A. the graph represents a relation because it contains ordered pairs (x,y). It is also a function because there are no repeating x values.
B. (0,0) (8,6)
slope = (6 - 0 ) / (8 - 0) = 6/8 = 3/4
so ur equation is : y = 3/4x or f(x) = 3/4x <===
C. the variable x represents the height of the building and the variable y (or f(x)) represents the total length of the shadow
