Question

M находится на линии AB, найдите ''у'', если A(-8;-6), B(-3;-1), M(5;y)​

Answer 1

Ответ:

-1-(-6)=5

Объяснение:

M(5;y)

y=yB-yA=-1-(-6)=5

M(5;5)

Answer 2

Given Information:

We are given the coordinates of points A(-8, -6), B(-3, -1), and M(5, y). We need to find the value of y for point M.

Solution:

To find the value of y for point M, we need to find the equation of the line AB and substitute the x-coordinate of point M into the equation to solve for y.

Equation of a Line:

The equation of a line passing through two points (x1, y1) and (x2, y2) can be found using the slope-intercept form:

y - y1 = m(x - x1)

where m is the slope of the line.

Finding the Slope:

The slope of the line AB can be found using the formula:

m = (y2 - y1) / (x2 - x1)

Substituting the coordinates of points A and B, we have:

m = (-1 - (-6)) / (-3 - (-8))

Simplifying the equation, we get:

m = 5 / 5 = 1

Equation of Line AB:

Using the slope-intercept form, we can write the equation of line AB as:

y - (-6) = 1(x - (-8))

Simplifying the equation, we get:

y + 6 = x + 8

Substituting the x-coordinate of Point M:

Substituting the x-coordinate of point M, which is 5, into the equation of line AB, we have:

y + 6 = 5 + 8

Simplifying the equation, we get:

y + 6 = 13

Subtracting 6 from both sides of the equation, we get:

y = 13 - 6 = 7

Answer:

The value of y for point M is 7.
