Question

Игрик равно кх плюс 7 проходит через точку А найти значение к если А равно (1,9) помогите

Answer 1

Y=kx+7
A(1;9)
9=k*1+7
k=9-7=2
k=2 , y=2x+7
ответ: k=2

Answer 2

Finding the Value of k when A is (1,9) in the Equation y = kx + b

To find the value of k when point A is (1,9) in the equation y = kx + b, we can use the given information and the equation of a line to solve for k.

Given: - Equation of a line: y = kx + b - Point A: (1,9)

We can use the coordinates of point A to solve for k.

Using the equation of a line, we can substitute the coordinates of point A into the equation to solve for k:

9 = k(1) + b

We also have information about the line from the search results: - The line equation is y = -4x + b - The point (-3, 2) lies on the line

Substituting the coordinates of point A into the equation, we get: 9 = k(1) + b

From the search results, we know that the line equation is y = -4x + b and the point (-3, 2) lies on the line .

Calculating the Value of k

Using the given equation of the line and the coordinates of point A, we can solve for k:

9 = k(1) + b

From the search results, we know that the line equation is y = -4x + b and the point (-3, 2) lies on the line .

By substituting the coordinates of point A into the equation, we get: 9 = k(1) + b

We can use the information from the search results to solve for k.
