Graphing Calculator

Good morning my friends, i am back today with graphing calculator online for free, i just wanted you to know that along with online math help we also have many sites which will help you even in graphing, look for such sites.

Well, you have know the uses of factoring calculator lets look for a problem which will help us solve a problem below and this will give you a clear picture on graphing calculator.

Problem No1:-

Solve the given system of equations by graphing calculator,

y = 5x + 15

y = x + 5

Solution:

Arrange the given equation in standard form,

5x - y = -15 equation 1

x - y = -5 equation 2


5x - y = -15

x - y = -5 (subtracting)

4x = -10

4x = -10

Divide 4 on both sides,

4x/4 = -10/4

x = -2.5

Plug in the x value in equation 1.

4(-2.5) - y = -15

-10 - y = -15

Add 10 on both sides

-10 + 10 - y = -15 + 10

-y = -5

y = 5

The graphing points are (-2.5, 0) and (0, 5). Look at the graph below.



We will work on quadratic formula calculator in our next post. Do you have some topic that you want me to discuss let me know that and i will work on it....
