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 (2,3)(2, -3) and is parallel to the line given by the equation 5x2y=25x - 2y = 2, 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 y=mx+by = mx + b, where mm is the slope.

The equation is: 5x2y=25x - 2y = 2 Solve for yy: 2y=5x+2-2y = -5x + 2 y=52x1y = \frac{5}{2}x - 1 So, the slope mm of the given line is 52\frac{5}{2}.

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 52\frac{5}{2}.

Step 3: Use the point-slope form

Now, use the point-slope form of the equation of a line: yy1=m(xx1)y - y_1 = m(x - x_1) where (x1,y1)(x_1, y_1) is the point the line passes through, and mm is the slope. Here, the point is (2,3)(2, -3) and the slope is 52\frac{5}{2}.

Substitute the values into the formula: y(3)=52(x2)y - (-3) = \frac{5}{2}(x - 2) y+3=52(x2)y + 3 = \frac{5}{2}(x - 2)

Step 4: Simplify the equation

Distribute the slope: y+3=52x5y + 3 = \frac{5}{2}x - 5 Now, subtract 3 from both sides: y=52x53y = \frac{5}{2}x - 5 - 3 y=52x8y = \frac{5}{2}x - 8

Final Answer:

The equation of the line is: y=52x8y = \frac{5}{2}x - 8
