❣Hola guys!
Alice and Emy are two students are of class 9. They together contributed Rs.100 towards the Prime Minister's Relief Fund to help the earthquake victims. Write a linear equation which satisfies this data. (You may take their contributions as Rs. x and Rs. y..
Draw the graph of the same.
No spamming.

Method to draw the graph of linear equation in
two variables:
1.Let the linear equation in two variables be ax+by+c=0
Write the linear equation and Express Y in terms
of x.
Y=(-ax+c)/b......(1)
2.Put put arbitrary value of x in equation 1 and
find the corresponding values of y.
3.Form a table by writing the value’s of y to the
corresponding values of x.
4.Draw the coordinates axes on graph paper and take
a suitable scale to plot points from the table on graph paper.
5.Join the points and we get a straight line and
produced it on both sides.
Hence, the straight line so obtained is the
required graph of given linear equation.
It is enough to plot two points Corresponding to
two solutions and join them by a line.

Solution:
[Table and graph are on the attachment]
Let the contributions of Yamini and Fatima
together towards the Prime Minister relief fund to help the earthquake victims
are ₹X and ₹Y.
A.T.Q
X+y=100......(1)
Here,We plot the points B(0,100) & A(100,0)
on graph paper and join all these points
to form a line AB.

Hope this will help you......
Hi Alexa, Below answer is according to class 10th..... This is correct.....
Let contribution of Alice be x
Let contribution of Emy be y
So, x+y=100
To draw graph, we need two solutions.
If x=0
0+y=100
y=100
If y=0
x+0=100
x=100
So two solutions are (0,100) and (100,0)
FOR GRAPH LOOK IN THE PICTURE ABOVE....
