Math Problem Statement
write the equation in point-slope form of the line that passes through the given point with the given slope: (-3, -5); m = -2
Solution
The point-slope form of a linear equation is:
Where:
- is a point on the line.
- is the slope.
In this case, the point is and the slope .
Substituting these values into the formula:
Simplifying:
This is the equation of the line in point-slope form.
