Math Problem Statement
Hilda wrote an equation of a line that passes through the point (2,‒3) parallel to the line y = ‒4x – 5. Which equation represents Hilda’s equation? Group of answer choices
y = ‒4x + 5
y = ‒4x + 9
x ‒ 4y = – 3
4x + y = 2
Solution
To solve this, we need to find the equation of a line passing through the point (2, ‒3) and parallel to the line given by .
Step 1: Identify the slope of the parallel line.
The slope-intercept form of a line is , where is the slope and is the y-intercept. From the equation , the slope is .
Since Hilda's line is parallel to this line, it will have the same slope, so the slope of Hilda's line is also .
Step 2: Use the point-slope form to find the equation.
The point-slope form of a line is given by:
Where is a point on the line, and is the slope. Substituting the point and the slope :
Step 3: Check the options.
The correct equation is .
Answer:
The correct equation is .
