Math Problem Statement

What is the equation of a line that is parallel to 2x-3=y and goes through the poiny (-5,3)

Solution

The given equation of the line is:

2x3=y2x - 3 = y

Step 1: Find the Slope

Rewriting the equation in slope-intercept form (y=mx+by = mx + b):

y=2x3y = 2x - 3

The slope (mm) of this line is 2.

Step 2: Use the Point-Slope Formula

A parallel line must have the same slope, so it will also have m=2m = 2. Using the point-slope form of a line:

yy1=m(xx1)y - y_1 = m(x - x_1)

where (x1,y1)=(5,3)(x_1, y_1) = (-5,3) and m=2m = 2, we substitute:

y3=2(x+5)y - 3 = 2(x + 5)

Step 3: Convert to Slope-Intercept Form

Expanding:

y3=2x+10y - 3 = 2x + 10

y=2x+13y = 2x + 13

Final Answer:

The equation of the required parallel line is:

y=2x+13y = 2x + 13
