Question

Нужна помощь!!! Какой формулой заданы координаты (1; 1) и (2; -3)? (линейная функция)

Answer 1

Может быть для 1. y=kx+1 (1;1)
y = kx, то
1=1k
k=1/1
k=1 проходящая через точку 1
--------------------------------------------------------------
(2;-3)
-3=2k
k=-3/2
k=-3/2 проходящая через точку -3/2

Answer 2

Linear Function Formula for Given Coordinates

To find the linear function formula for the given coordinates (1, 1) and (2, -3), we can use the formula for the slope of a line, which is given by Y = mX + c, where m is the slope and c is the y-intercept.

First, let's calculate the slope (m) using the given coordinates: m = (Y2 - Y1) / (X2 - X1)

Substitute the given coordinates: m = (-3 - 1) / (2 - 1) = -4 / 1 = -4

Now that we have the slope, we can use one of the given points to find the y-intercept (c). Let's use the point (1, 1): 1 = -4(1) + c c = 1 + 4 = 5

So, the linear function formula for the given coordinates is: Y = -4X + 5

Conclusion

The linear function formula for the given coordinates (1, 1) and (2, -3) is Y = -4X + 5.
