Question

If the points A(3,5) and B(1,4) lie on the graph of the line ax+ by = 7, find the values of a and b.

Answer 1

Answer:

yes 3,5 add both that is the value of a of mate

Answer 2

Answer:

A(3,5) and B(1,4)

$x_{1}=3 \\y_{1} =5\\x_{2} =1\\y_{2} =4\\ax+by=7$

On a line

$x=\frac{x_{1}+x_{2} }{2}\\y=\frac{y_{1}+y_{2} }{2}$

x=3+1/2

y=5+4/2

x=4/2

y=9/2

x=2

y=4.5

2a+9/2b=7
