To find the equation of the line that is parallel to \( y = 25x + 1 \) and passes through the point \( (5, 5) \), we start by recognizing that parallel lines have the same slope. The slope of the given line \( y = 25x + 1 \) is \( 25 \).

Next, we can use the point-slope form of the line equation, which is given by:

\[ y - y_1 = m(x - x_1) \]

where \( (x_1, y_1) \) is a point on the line and \( m \) is the slope. Here, \( (x_1, y_1) = (5, 5) \) and \( m = 25 \).

Plugging in the values:

\[ y - 5 = 25(x - 5) \]

Now, simplify the equation:

\[ y - 5 = 25x - 125 \]

Add \( 5 \) to both sides:

\[ y = 25x - 120 \]

Thus, the line that is parallel to \( y = 25x + 1 \) and passes through the point \( (5, 5) \) is:

\[ y = 25x - 120 \]

So, the blank in your equation \( y = 25x + \text{blank} \) is \( -120 \).

Final answer: The line is \( y = 25x - 120 \).

What value completes the equation of the line that is perpendicular to the line y=−34x+7 and goes through the point (6,1) ?(1 point) The line that is perpendicular to y=−34x+7 and passes through the point (6,1) is y=43x+blank.

To find the equation of the line that is perpendicular to the line \( y = -34x + 7 \) and passes through the point \( (6, 1) \), we first need to determine the slope of the given line and then find the slope of the perpendicular line.

  1. Identify the slope of the given line:
    The slope \( m \) of the line \( y = -34x + 7 \) is \( -34 \).

  2. Determine the slope of the perpendicular line:
    The slope of a line that is perpendicular to a given line is the negative reciprocal of the slope of that line. Therefore, the slope \( m_{\perp} \) of the perpendicular line is: \[ m_{\perp} = -\frac{1}{-34} = \frac{1}{34} \]

  3. Use the point-slope form of the line equation:
    The point-slope form is given by: \[ y - y_1 = m(x - x_1) \] where \( (x_1, y_1) = (6, 1) \) and \( m = \frac{1}{34} \).

Substituting in the values, we have: \[ y - 1 = \frac{1}{34}(x - 6) \]

  1. Simplify the equation:
    Distributing the slope on the right side: \[ y - 1 = \frac{1}{34}x - \frac{6}{34} \] \[ y - 1 = \frac{1}{34}x - \frac{3}{17} \]

Now, add \( 1 \) (which is \( \frac{17}{17} \)) to both sides: \[ y = \frac{1}{34}x - \frac{3}{17} + \frac{17}{17} \]

Combine the constant terms on the right: \[ y = \frac{1}{34}x + \left(\frac{17}{17} - \frac{3}{17}\right) \] \[ y = \frac{1}{34}x + \frac{14}{17} \]

Now, we want to write the equation in the desired form \( y = 43x + \text{blank} \). Notice that \( \frac{1}{34} = \frac{43}{34} \), so we can express this as: \[ y = \frac{43}{34}x + \frac{14}{17} \]

However, this won't match your requested format exactly. Instead, let's convert \( \frac{14}{17} \) into a decimal or a more manageable fraction.

  1. Finding the blank:
    Since \( y = 43x + \frac{14}{17} \), the blank in your original format \( y = 43x + \text{blank} \) corresponds to \( \frac{14}{17} \).

To summarize, the line that is perpendicular to \( y = -34x + 7 \) and passes through \( (6, 1) \) can be expressed as: \[ y = 43x + \frac{14}{17} \]

So, the value that completes the equation is \( \frac{14}{17} \).
