The median is 65
$60 + 70 = 130 \\ 130 \div 2 = 65$
the 2nd and third quartile is 65
$50 + 60 + 70 + 80 = 260 \\ 260 \div 4 = 65$

P(4,-4) -->(-4, 7)

4 - 8 = -4 -------->left 8

-4 + 11 = 7 -------->up 11

Answer: left 8; up 11

C(3,-1) , left 4 up 1

3 - 4 = -1 -------->left 4

-1 + 1 = 0 -------->up 1

(x , y) -->(x - 4 , y +1)

C(3, -1) -->C'(-1 , 0)

(x , y) --> (x - 4, y + 1); (-1 , 0)

Line AB passes through points A(−6, 6) and B(12, 3). If the equation of the line is written in slope-intercept form, y=mx+b, the

san4es73 [151]

Answer:

We get value of the value of b = 5

Step-by-step explanation:

Line AB passes through points A(−6, 6) and B(12, 3). If the equation of the line is written in slope-intercept form, y=mx+b, then m=m equals negative StartFraction 1 Over 6 EndFraction.. What is the value of b?

We have slope m: $m=-\frac{1}{6}$

We need to find value of b (y-intercept)

Using the point A(-6,6) and slope $m=-\frac{1}{6}$ we can find b.

Using slope-intercept form, putting values of m and x and y we get the value of b:

$y=mx+b\\6=-\frac{1}{6}(-6)+b\\6=1+b\\b=6-1\\b=5$

So, we get value of the value of b = 5
