Math Problem Statement
What is an equation of the line that passes through the point (2,−3) and is parallel to the line 5x − 2y = 2
Solution
To find the equation of the line that passes through the point and is parallel to the line given by the equation , follow these steps:
Step 1: Find the slope of the given line
Start by rewriting the equation of the given line in slope-intercept form , where is the slope.
The equation is: Solve for : So, the slope of the given line is .
Step 2: Use the slope of the parallel line
Since parallel lines have the same slope, the slope of the line we are looking for is also .
Step 3: Use the point-slope form
Now, use the point-slope form of the equation of a line: where is the point the line passes through, and is the slope. Here, the point is and the slope is .
Substitute the values into the formula:
Step 4: Simplify the equation
Distribute the slope: Now, subtract 3 from both sides:
Final Answer:
The equation of the line is:
