The answer is (-0.5, 2.25).

<u>Explanation:</u>

A = (0,4)

B = (-2,-3)

The line joining the two points from A to B can be represented as a vector:

r (x) = A + x*(B - A)  ,  where  0<= x <= 1

Now, r (x) can be written as:

r (x) = (0,4) + x[ (-2,-3) - (0,4) ] = (0,4) + x (-2,-7)

Assuming x to be 1/4 (given)

x(1/4) = (0,4) + 1/4* (-2,-7) = (0 -1/2, 4  -7/4) = (-1/2, 9/4)  

= (−0.5, 2.25)

Solution

Find the mid point of A and B.

The mid point of A and B is (-1. 0.5)

Now find mid point of (0, 4) and (-1, 0.5)

= [(0 + (-1)/2 , (4 +0.5)/2 ]

= (-1/2, 4.5/2)

= (-0.5, 2.25)

The answer is (-0.5, 2.25)


Thank you.

Given the point (1, 3) and a slope of 2, write an equation in point-slope form.
Sunny_sXe [5.5K]

Answer:

y=2x+1

Step-by-step explanation:

Since we are given a point and a slope, we can use the point slope formula

y-y_{1} =m(x-x_{1})

m is the slope. In this case, m is 2.

y1 is the y coordinate of the point given. y1 is 3.

x1 is the x coordinate of the point given. x1 is 1

y-3=2(x-1)

Now, we need to get the equation into point slope form: y=mx+b

To do this, we need to get y by itself

First, distribute the 2 on the right

y-3=2*x+ 2*-1

y-3=2x-2

Add 3 to both sides

y-3+3=2x-2+3

y=2x+1

The equation is in y=mx+b form, so our final equation is:

y=2x+1

Y=x+4, 2x+y=13 solve the following system of equation. Please help
alexandr1967 [171]
Well you have to subtract -2 to both sides and it well look like Y= -2+13 and then y=x+4
