Lesson Steps

Step Type Explanation Answer

1

Problem

Find the equation of the line passes through the point and origin:
\$ (0,0),(5,9) \$

2

Formula:

Consider given points as \$(x_1,y_1)\$ and \$(x_2,y_2)\$

\$ x_1=0,y_1=0 and x_2=5,y_2=9 \$

3

Hint

Using Two point form : \$(y - y_1) = (y_2 - y_1) / (x_2 - x_1)(x - x_1)\$

\$ (y - 0) = (9 - 0) / (5 - 0)(x - 0) \$

4

Step

After Simplification

\$ y = 9 / 5x \$

5

Step

Move 5 to Right side

\$ 5y = 9x \$

6

Step

Converting to the equation form

\$ 9x - 5y = 0 \$
