Lesson Steps
| Step | Type | Explanation | Answer |
|---|---|---|---|
1 |
Problem |
Find the equation of the line passes through the points: |
|
2 |
Step |
Consider given points as (x_1,y_1) and |
\$(x_2,y_2)\$ |
3 |
Step |
equating the terms |
\$ x_1=-3 , y_1=1 , x_2=2 & y_2=-5 \$ |
4 |
Formula: |
Equation of line passing through two points is |
\$(y - y_1) = (y_2 - y_1) / (x_2 - x_1)(x - x_1)\$ |
5 |
Step |
by simplifying |
\$(y - 1) = (-5 - 1) / (2 -(-3))(x -(-3)) \$ |
6 |
Step |
after simplification |
\$ (y - 1) = (-5 - 1) / (2 + 3)(x + 3) \$ |
7 |
Step |
Simplifying the equation |
\$ (y - 1) = (-6) / (5)(x + 3) \$ |
8 |
Step |
simplifying the equation |
\$ 5(y - 1) = -6(x + 3) \$ |
9 |
Step |
by simplifying |
\$ 5y - 5 = -6x - 18 \$ |
10 |
Step |
after simplifying the equation |
\$ 6x + 5y - 5 + 18 = 0 \$ |
11 |
Step |
after simplification |
\$ 6x + 5y + 13 = 0 \$ |
