Math Problem Statement
Solution
The problem in the image asks to write the equation of a line parallel to the line and passing through the point (-2, 5).
Steps to solve:
-
Find the slope of the given line: The given line is . We can rewrite it in slope-intercept form , where is the slope.
So, the slope of the line is .
-
Use the same slope for the parallel line: Lines that are parallel have the same slope. Therefore, the line we need to find will also have a slope of .
-
Use the point-slope form of a line: The point-slope form of a line is: where is the point the line passes through, and is the slope. In this case, the point is and the slope .
Substituting the values:
-
