Given the line parallel to the line y=2x−5
and passes through the point (−3,−4).
Which of the algebraic representations is the corresponding one for the given line?
To solve this problem, follow these steps:
- Step 1: Identify the given line's slope. The given line is y=2x−5, which has a slope of 2.
- Step 2: Since the line we want is parallel, it will have the same slope, m=2.
- Step 3: Use the point-slope formula, y−y1=m(x−x1). Given point is (−3,−4).
- Step 4: Substitute m=2, x1=−3, and y1=−4 into the point-slope formula:
y−(−4)=2(x−(−3))
- Step 5: Simplify the equation:
y+4=2(x+3)
- Step 6: Distribute the 2:
y+4=2x+6
- Step 7: Solve for y:
y=2x+6−4
- Step 8: Simplify further:
y=2x+2
The corresponding equation of the line parallel to y=2x−5 and passing through (−3,−4) is y=2x+2. When compared to the choices given, the correct choice is:
y=2x+2
