Answer 2

The value of p from the given linear equation at the designated values is 7.

Given

The equation is $2x+3y=p$

$x=2 \text { and }y=1$

To find:

the numerical value of p

Solution:

The equation $2x+3y=p$ represents a straight line in the co-ordinate plane.

The line is of the form $y=mx+c$  where c is the y-intercept of the straight line and m is the slope of the straight line and .

To find the value of p we have to substitute the given values of x and y in the equation and solve for p.

The values of x and y represent a point on the co-ordinate axes.

So we will substitute "x" and "y" to find p.

$2x+3y=p\\\\or, 2\times 2+3 \times 1 =p\\\\or, 4+3=p\\\\or, p=7$

Therefore from the given linear equation at the specified point we get the value of p as 7.
