Answer:
Step-by-step explanation:
We are given;
The equation of a line;
We are required to determine the equation of a line perpendicular to the above line and passing through (-2, -2).
- We can get the gradient of a line when given its gradient and a point where it is passing through.
- In this case;
We need to know that the product of gradient of two parallel lines is -1
- Therefore, we can get the gradient of the unknown line;
m₁× m₂ = -1
Thus;
m₂ = -1 ÷ -2/3
= 3/2
Thus, the gradient is 3/2 and the line passes through (-2,-2)
Thus, to get its equation, we take another point (x,y)
We get;
Then;
Combining the like terms,
In the form of slope-intercept;
