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 y=4x5y = -4x - 5.

Step 1: Identify the slope of the parallel line.

The slope-intercept form of a line is y=mx+by = mx + b, where mm is the slope and bb is the y-intercept. From the equation y=4x5y = -4x - 5, the slope is m=4m = -4.

Since Hilda's line is parallel to this line, it will have the same slope, so the slope of Hilda's line is also m=4m = -4.

Step 2: Use the point-slope form to find the equation.

The point-slope form of a line is given by:

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

Where (x1,y1)(x_1, y_1) is a point on the line, and mm is the slope. Substituting the point (2,3)(2, -3) and the slope m=4m = -4:

y(3)=4(x2)y - (-3) = -4(x - 2) y+3=4(x2)y + 3 = -4(x - 2) y+3=4x+8y + 3 = -4x + 8 y=4x+83y = -4x + 8 - 3 y=4x+5y = -4x + 5

Step 3: Check the options.

The correct equation is y=4x+5y = -4x + 5.

Answer:

The correct equation is y=4x+5y = -4x + 5.
