Determine if the point 3-4 is a solution for the equation y equals 8 -4x?
use the formula y-y1=m(x-x1)
When using the slope formula does it have to be (y2-y1)(x2-x1) or can it be (y1-y2)(x1-x2)?
If you mean: (y2-y1)/(x2-x1) and (y1-y2)/(x1-x2) then either works out the same.
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) )
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
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
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
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).
How do you write X equals -8 in its exponential form?
X1 = -81
What is the vaule of x1?
X or if it says what "x" equals then plug that in and multiply
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.
Show magnitude in a graph?
the absolute value of displacement which is delta equals x2-x1
