Question

1) The line 3x+2y = -2 intersects the Y-axis at...........
a) (0,-1) b) (-1,0) c)(3,0) d) (0,3)​

Answer 1

Answer:

c is the answer please mark my marks

Answer 2

$1. The \: line\: 3x + 2y = -2 \: intersects \:the \\Y-axis \: at \: \underline { \green { \: ( 0 , - 1 ) }}$

Therefore.,

$Option \: \green { ( a ) } \: is \: correct .$

Explanation:

$Given \: linear \: equation \: in \: two \\variables \: x \: and \: y \: is \: 3x + 2y = -2$

$To \: find \: the \: intersecting \: point \: at \\Y-axis , we \: must \: put \:x = 0 \: in \:the \\ equation$

$3 \times 0 + 2y = -2$

$\implies 2y = -2$

$\implies y = \frac{-2}{2}$

$\implies y = -1$

Therefore.,

$\red{ Required \: point }\green { = ( 0 , -1 ) }$
