This would have to apply for a certain height compared to a weight or vice versa. I'm 5'8'' and for me that would mean I would have a healthy weight of 140 lbs.

What is the equation of the given line in the point slope -form ?
ladessa [460]

Answer:

see below

Step-by-step explanation:

We are given two points (3,4) and (0,1)

so we can find the slope

m = ( y2-y1)/(x2-x1)

    = (1-4)/(0-3)

  = -3/-3

  = 1

The point slope form is

( y-y1) = m(x-x1)

y - (4) = 1 (x-3)

y - (4) =  (x-3)

or using the other point

y - 1 = 1( x-0)

y - 1 = x

What is the distance between A(-8, 4) and B(4, -1)?
Anettt [7]

Answer:

The distance between A(-8, 4) and B(4, -1) is 13 units.

Step-by-step explanation:

To find the distance between any two points, we can use the distance formula given by:

\displaystyle d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2

We have the two points A(-8, 4) and B(4, -1). Let A(-8, 4) be (<em>x₁, y₁</em>) and let B(4, -1) be (<em>x₂, y₂</em>). Substitute:

d=\sqrt{(4-(-8))^2+(-1-4)^2}

Evaluate:

d=\sqrt{(12)^2+(-5)^2}

So:

d=\sqrt{144+25}=\sqrt{169}=13\text{ units}

The distance between A(-8, 4) and B(4, -1) is 13 units.

Write an equation in point-slope form of the line that passes through the given point and with the given slope m.
il63 [147K]

y = mx + c

7 = 4(-8) + c

c = 39

The equation is y = 4x + 39

y - 7 = 4 ( x - (-8))

y -7 = 4 (x +8)

SOLVE EACH SYSTEM USING SUBSTITUTION
NNADVOKAT [17]
1. since the equations equal each other 
2x+19=x+7
-x        -x
x+19=7
  -19  -19
x= -12
sub into y= x+7
y= -12+7
y= -5

2. x+2y=-7
<span>x+y+23=0
i don't know what the second equation is equal to, i'll assume 0

2y=x-7
y=1/2x-7/2
sub this into x+y+23=0
x+1/2x-7/2+23=0
3/2x+39/2=0
       -39/2   -39/2
3/2x= -39/2
x=-39/2 / 3/2
x= -13
sub into y=1/2x-7/2
y=1/2(-13)-7/2
y= -10

3. </span>x+5y=2
<span>x=-4y+5
</span>sub x=-4y+5 into x+5y=2
-4y+5+5y=2
y+5=2
  -5  -5
y= -3
sub y =-3 into x =-4y+5
x=-4(-3)+5
x= 17

4. 3x+y=9
<span>y=-5x+9
</span>sub -5x+9 into 3x+y=9
3x+(-5x+9)=9
3x-5x+9=9
-2x+9=9
     -9  -9
-2x=0
x=0
sub into y=-5x+9
y=-5(0)+9
y=9
