find the point of intersecrion of X-axis and the line x-y=4
Answers
Answer:
Step-by-step explanation:
The line x - y = 8 will intersect the y-axis when x = 0 since every point on the y-axis has an x-coordinate of 0, i.e., (x, y) = (0, b), where y = b when x = 0; therefore, to find the point of intersection (0, b) between the line x - y = 8 and the y-axis, we set x = 0 and then solve for y = b as follows:
x - y = 8
0 - b = 8
0 + (-b) = 8
-b = 8
(-1)(-b) = (-1)8
b = -8
Therefore, ...
The point at which the line x - y = 8 intersects the y-axis is: (0, b) = (0, -8)

It intersects the y axis when the x value is equal to 0.
x - y = 8
x = 8 + y
Since we want x to be 0, we can say
0 = 8 + y
y = -8
So that intersection point is (0; -8).

Step-by-step explanation:
Let x = x and let y = y therefore x +y = 4
•xy = 4
• therefore. xy = 4
