Chapter 2: Q27. (page 66)

Write each equation in standard form. Identify A,B and C.

y=-3x+4

Short Answer

Expert verified

The required values are A=3,B=1,C=4.

Step by step solution

01

– Standard form of a linear equation.

The standard form of a linear equation is Ax+By=C, where A鈮�0,A and B are not both zero.

02

– Rewrite the given linear equation in the standard form.

The given equation is:

y=-3x+4

Add 3x on both sides.

y+3x=鈭�3x+4+3xy+3x=43x+y=4

03

– Find the required values.

Now compare the equation 3x+y=4with the standard form of the linear equation Ax+By=Cto find the values of A,B,C.

A=3B=1C=4

Thus, the required values are A=3,B=1,C=4.
