Question

plot a graph for equations and same the region bounded by two lines have and x axis I want the four solution according to this question for equation for 4x minus
3 Y + 4 = 0
4 X + 3 Y - 20=0
​

Answer 1

The given set of linear equations are 4x-3y+4 =0 ......(1) and 4x+3y-20=0.......(2)

first we will plot these straight lines.

points (-1,0) and (0,3/4) satisfy the eq(1) plot the points and join them

points (5,0) and (5/4 ,5) satisfy eq(2) plot the points and join them.

now from the graph it is clear that the given lines intersect at point (2,4)

thus x =2 and y =4 is the solution of the given equation.

the shaded region is the required region.

area of the triangle ABC = 1/2 *base*height of the triangle ABC

= 1/2 *BC*4

=2BC

=2*6=12 sq units

hope this helps you.

cheers!!
