Question

The graph of the linear equation 4x+3y=12 cuts the x-axis at the point

Answer 1

Answer:

When the graph cuts x-axis, y coordinate becomes zero.

⇒4x+3(0)=12

⇒4x=12

⇒x=3

Similarly, when the graph cuts the y-axis, x coordinate is zero.

⇒4(0)+3y=12

⇒3y=12

⇒y=4

If OA=3units

OB=4units

By Pythagoras theorem

(AB)2=(OA)2+(OB)2

=(3)2+(4)2

=9+16

=25

=25

⇒AB=5units

When the graph cuts x-axis, y coordinate becomes zero.

⇒4x+3(0)=12

⇒4x=12

⇒x=3

Similarly, when the graph cuts the y-axis, x coordinate is zero.

⇒4(0)+3y=12

⇒3y=12

⇒y=4

If OA=3units

OB=4units

By Pythagoras theorem

(AB)2=(OA)2+(OB)2

=(3)2+(4)2

=9+16

=25

=25

⇒AB=5units

When the graph cuts x-axis, y coordinate becomes zero.

⇒4x+3(0)=12

⇒4x=12

⇒4(0)+3y=12

⇒3y=12

⇒y=4
