Value of `y` decreases exponentially from `y =10` to `y =6`. plot `a x-y` graph.

Value of y increases exponentially from y =- 4 to y = + 4 . Plot a x-y graph.

Value of y increases exponentially from y =- 4 to y = + 4 . Plot a x-y graph.

Find y, if x +y=10 and 3y-x =6 .

Draw the graph of y=(x+2)/(3) , Find the value of y where x=-2 from the graph. Also find from the graphs the value of x for which the value of y is 3.

From the graph y = cos x , draw |y| = cos x .

(a) Draw the graph of the equation 2y-3x=7 Also find the value of y when x=2(1)/(2) and the value of x when y=3(1)/(2) from the graph.

On the same graph paper, plot the graphs of y=2x-1, y=2x and y=2x+1 from x=-2 to x=4 Are the graph (lines) drawn parallel to each other?

Draw the graph of the equation 2x + 3y = 11. Find the value of y when x = 1 from the graph.

Draw the graph of the equation 2x + 3y = 11. Find the value of y when x = 1 from the graph.
