Answer:
y=6/5x+2
Step-by-step explanation:
1.find the slope(m)
m=y2-y1/x2-x1
m=14-(-4)/10-(-5)
m=14+4/10+5
m=18/15
m=6/5
y-y1=m(x-x1)
y-(-4)=6/5(x-(-5))
y+4=6/5(x+5)
y+4=6/5x+30/5
y=6/5x+30/5-4
y=6/5x+10/5
y=6/5x+2
First one is D and second one is C
Answer:
1). The constant of variation is 7
2). w = 6 for the given values of x and y
Step-by-step explanation:
"Varies jointly" tells us that y is a direct result of a mathematic operation involving x and w. We will assume y is directly prorportional to x and w, in the sense that we can find a multiplicative relationship of the form y=Kxw, where K is the constant of variation.
We are given one data point: y=-42 where x is 2 and w is -3. Let's put those values into our trrial expression:
y=Kxw
-42=K(2)(-3)
-42 = -6K
K = 7
<h2>The expression becames <u>
y = 7xw</u></h2>
The constant of variation is 7.
The value of w for y=3 and x=(1/14) would be:
y=7xw
3 = 7*(1/14)*w
3 = (1/2)*w
<h2><u>
w = 6</u></h2>
