V = (-7,-4)

8v would be 8 times both numbers

8v = (8*-7, 8*-4)

8v = (-56, -36)

magnitude = square root( -56^2 + -36^2)
 = sqrt(3136 + 1296)
= sqrt(4432 )
 = 4 sqrt(277)

What is the slope and b value of this graph?​
Taya2010 [7]
Your B, or y-intercept, is 3(the y-intercept is the point at which your line crosses the y-axis)
Your slope is -2
-EXPLANATION-
When using the points given, (0,3) and (1,1) you will use the following formula:
M=y₂-y₁ / x₂-x₁
y2 being 1
y1 being 3
x2 being 1
x1 being 0
-solving-
M=1-3/1-0
M=-2/1
-2 divided by 1 is -2 making that your slope.
If you need it to be written in slope intercept form(y=mx+b), write it like this:
y=-2x+3
I hope this helped :)

2/3 x + 1/2 equals 3/4 + 5/3 ​
worty [1.4K]
2/3x + 1/2 = 3/4 + 5/3
2/3x + 1/2 - 1/2 = 3/4 + 5/3 - 1/2
2/3x = 3/4 + 5/3 - 1/2
2/3x = 3/4(3/3) + 5/3(4/4) - 1/2(6/6)
2/3x = 9/12 + 20/12 - 6/12
2/3x = 23/12
2/3x(3/2) = 23/12(3/2)
X = 69/24
X = 2 21/24
X = 2 7/8
