Question

1) To draw the graph of 4x+5y=6.
y=
when x=4*
A) 2
B] -2
C] O
D] -4​

Answer 1

$\huge \tt \underline{Given : }$

$\tt \: x = 4$

$\tt \: th e \: equation \: is \: (4x + 5y = 6)$

$\huge \tt \underline{To \: find : }$

$\tt \: the \: value \: of \: (y).$

$\huge \tt \underline{Solution : }$

$\tt4(4) + 5y = 6$

$\tt16 + 5y = 6$

$\tt5y = 6 - 16$

$\tt5y = - 10$

$\tt \: y = \frac{10}{ - 5}$

$\tt \: y = - 2$

• Therefore the value of Y = -2

• So that option [B] is correct

Now,

• Plot a graph of (4 , -2) .
