Q. Find the slope of the line \(y = 12x + \tfrac{1}{6}\).

Answer

The slope is the coefficient of x, so \(m = 12\).

Detailed Explanation

  1. Recognize the form of the equation.

    The slope-intercept form of a line is given by \(y = mx + b\), where \(m\) denotes the slope and \(b\) denotes the y-intercept. When an equation is written in this form, the coefficient of \(x\) is the slope.

  2. Write down the given equation.

    The line is \(y = 12x + \tfrac{1}{6}\).

  3. Identify the slope from the equation.

    Comparing \(y = 12x + \tfrac{1}{6}\) with \(y = mx + b\), the coefficient of \(x\) is \(m = 12\). Therefore the slope is 12.

  4. (Optional) Verify by using two points and the rise-over-run formula.

    Choose two x-values, for example \(x_1 = 0\) and \(x_2 = 1\).

    Compute corresponding y-values:

    \(y_1 = 12(0) + \tfrac{1}{6} = \tfrac{1}{6}\), so the point is \((0,\tfrac{1}{6})\).

    \(y_2 = 12(1) + \tfrac{1}{6} = 12 + \tfrac{1}{6} = \tfrac{73}{6}\), so the point is \((1,\tfrac{73}{6})\).

    Compute the slope using rise over run:

    \(m = \dfrac{y_2 – y_1}{x_2 – x_1} = \dfrac{\tfrac{73}{6} – \tfrac{1}{6}}{1 – 0} = \dfrac{\tfrac{72}{6}}{1} = \dfrac{12}{1} = 12\).

    This confirms the slope is 12.

Answer: The slope of the line is 12.

Algebra FAQs

What is the slope of the line given by \(y=12x+ \tfrac{1}{6}\)?

The equation is in slope–intercept form \(y=mx+b\), so the slope \(m\) is \(12\).

How do you identify the slope from \(y = mx + b\)?

In \(y=mx+b\) the coefficient \(m\) of \(x\) is the slope. The constant \(b\) is the \(y\)-intercept.

How do you find the slope from two points (x1, y1) and (x2, y2)?

Use \( m = \frac{y2-y1}{x2-x1} \). It measures rise over run; undefined if \( x2=x1 \) (vertical line).

How do you get the slope from standard form \(Ax+By=C\)?

Rewrite as \(y=mx+b\) by solving for \(y\): \(y = -\frac{A}{B}x + \frac{C}{B}\). The slope is \(m = -\frac{A}{B}\)..

What is the slope of a line perpendicular to \(y=12x+\tfrac{1}{6}\)?.

Perpendicular slopes are negative reciprocals. For \(m=12\), the perpendicular slope is \(-\tfrac{1}{12}\)..

What is the slope of a line parallel to \(y=12x+ \tfrac{1}{6}\)?.

What is the slope of a line parallel to \(y=12x+ \tfrac{1}{6}\)?.

How does slope affect the steepness and direction of a line?

Larger \( |m| \) means steeper line. Positive \(m\) rises left to right; negative \(m\) falls left to right. \(m=0\) is horizontal; undefined slope is vertical.

How can you graph \(y = 12x + \tfrac{1}{6}\) quickly?

Start at y-intercept \(0, \tfrac{1}{6}\), then use rise/run of \(12 = \frac{12}{1}\): go right \(1\), up \(12\). Repeat to plot additional points.
The slope of y = 12x + 16 is 12 now.
