Determine if the point 3-4 is a solution for the equation y equals 8 -4x?
use the formula y-y1=m(x-x1)
How do you find a midpoint between two points on a graph?
Given two coordinates (x1,y1) and (x2,y2) The midpoint is ( ((x2+x1)/2) , ((y2+y1)/2) )
When using the slope formula does it have to be (y2-y1)(x2-x1) or can it be (y1-y2)(x1-x2)?
Oh, don't you worry, friend! When using the slope formula, whether you do (y2-y1)/(x2-x1) or (y1-y2)/(x1-x2), the answer will be the same! It's all about the difference in vertical and horizontal values, and as long as you stay consistent in your calculations, you'll find the slope just fine. Just trust your instincts and enjoy the process of solving the equation.
A statement that 2 ratios are equal?
A statement that two ratios are equal is called a proportion in math. An example of a proportion is 1/2 equals 2/4. In this proportion, if you cross multiply, you find that 4 x1 is equal to 2 x 2, which is a true statement or proportion.
Formula to find the midpoint in co-ordinate geometry?
midpoint=(X1 + X2, Y1 + Y2)divide both of those by 2.X1 + X2 divided by 2 should give you the co ordinate for X.
X plus one over x squared plus two?
it equals x1 it equals x1
which is the component form of AB?
The component form of a vector AB would typically be represented as (x2 - x1, y2 - y1), where A is at the point (x1, y1) and B is at the point (x2, y2).
Maxz equals 2x1 plus 2x2 stc 5x1 plus 3x2 equals 8 x1 plus 2x2 equals 4 x1 x2 equals 0 and integerssolve by ipp?

How matrix X1 X2 equals matrix X1 X2?
i think its pretty much the same thing because matrix X1 X2 IS ACTUALLY X1 X2
Find slope of the line ab?
If point a has coordinates (x1,y1), and point b has coordinates (x2, y2), then the slope of the line is given by the formula: m = (y2-y1)/(x2-x1).
Let A denote the event that the sum of 2 dice equals 11 Let x1 x2 denote the outcome first die equals x1 second die equals x2 Then?
A={(6,5),(5,6)} And The probability P(A) equals1/8
What is the vaule of x1?
X or if it says what "x" equals then plug that in and multiply
How do you write X equals -8 in its exponential form?
X1 = -81
What is the distance formula in geometry?
AB = sqrt (x2 - x1)2 + (y2 -y1)2 Sqrt is the square root of
What is the formula to calculate the slope?
It's m = y2 - y1/ x2- x1 It's m equals y2 minus y1 over x2 minus x1
What is true about pairs on a line for the line to have a positive slope?
If A = (x1, y1) and B = (x2, y2) then, if x1 ≠x2 the slope of AB is (y2 - y1)/(x2 - x1) There are various ways of interpreting slope > 0. One way is that it implies that y2 > y1 and x2 > x1 or y2 < y1 and x2 < x1 that is both the coordinates of one point are greater than both the coordinates of the other point. Note that if x1 = x2 then the slope is not defined.
If A(-2-4) and B(-8-4) what is the length of AB?
AB can be found by using the distance formula, which is the square root of (x2-x1)^2 + (y2-y1)^2. In this case, AB= the square root of (-2-(-8))^2 + (-4-(-4))^2 which AB= the square root of 64 + 0 which AB=8.
