Question

Y=kx+b A(2;0) B(0;-4)

Answer 1

У=кх+b

-2=к*0+b
-2=b
b= -2

-4=k*0+b
k+b=6
k=6

Ответ: k=6. b= -2

Answer 2

It seems like you're working with a linear equation in the form of y = kx + b and have two points A(2, 0) and B(0, -4). To find the values of k and b, you can use these points to set up a system of equations and solve for the variables.

Let's start with point A(2, 0):

y = kx + b 0 = k * 2 + b

Now, let's use point B(0, -4):

y = kx + b -4 = k * 0 + b

Since k * 0 is always 0, we can simplify the second equation:

-4 = b

Now, we can use this value of b and the equation from point A to solve for k:

0 = k * 2 + (-4) 0 = 2k - 4 2k = 4 k = 4 / 2 k = 2

So, the values of k and b for the equation y = kx + b are:

k = 2 b = -4

Therefore, the equation of the line passing through points A(2, 0) and B(0, -4) is y = 2x - 4.
