Answer:
The equation of the line AB is y - x -4 = 0
Step-by-step explanation:
The points are A (10,14) and B(2,6)
Now, slope of the line AB :
or, =
So, slope of the equation AB = 1
Now, by SLOPE INTERCEPT FORM:
The equation of line is given as : y - y0 = m (x-x0)
So,the equation of line AB is y - 6 = 1(x-2)
or, y - 6 -x + 2 = 0
or, y - x -4 = 0
Hence, the equation of the line AB is y - x -4 = 0
Hey there :)
Let us first translate words into mathematics!
Sum of 2 numbers is 52
x + y = 52
Difference of 2 numbers is 9
x - y = 9
(eq.1) x + y = 52
(eq.2) x - y = 9
Add both equations : x + y = 52
+ x - y = 9
2x = 61
x = 30.5
We now have the value of x, substitute into eithe formulae to find y
x - y = 9 , 30.5 - y = 9 , 30.5 - 9 = y , 21.5 = y
x + y = 52 , 30.5 + y = 52 , 52 - 30.5 = y , 21.5 = y
x = 30.5
y = 21.5
