Math Problem Statement

Write the equation of the line in standard with a slope of 1/4 and y-intercept of -2.

Solution

We are asked to write the equation of a line in standard form, given the slope of 14\frac{1}{4} and the y-intercept of 2-2.

Step 1: Recall the slope-intercept form

The slope-intercept form of a line is given by: y=mx+by = mx + b Where mm is the slope and bb is the y-intercept.

For this problem:

  • The slope m=14m = \frac{1}{4}
  • The y-intercept b=2b = -2

So, the equation in slope-intercept form is: y=14x2y = \frac{1}{4}x - 2

Step 2: Convert to standard form

The standard form of a line is written as: Ax+By=CAx + By = C Where AA, BB, and CC are integers.

To convert y=14x2y = \frac{1}{4}x - 2 into standard form:

  1. Multiply the entire equation by 4 to eliminate the fraction: 4y=x84y = x - 8
  2. Rearrange the terms so that the xx-term is on the left side: x4y=8x - 4y = 8

This is the equation of the line in standard form: x4y=8x - 4y = 8.

Final Answer:

x4y=8x - 4y = 8

Tip: Always ensure the coefficients in standard form are integers, and it's common to write the equation with a positive xx-coefficient.
