draw the graph of 9x-5y+160=0. From the graph find the value of y when x=5

first we will draw x-axis and y-axis.

9x-5y+160=0

plot the points. join the points to make the straight line.

now draw a line perpendicular to x-axis at point (5,0). let it intersect the line at point P.

from P draw a line parallel to x-axis, let it intersect y-axis at point Q. measure the coordinates of the point Q.

the value of ordinate at point Q is the value of y at x=5.

and the value of y at x=5 is 41.
