Math Problem Statement

Graph this line: y+5= 1/4 (x–1)

Solution

To graph the equation:

y+5=14(x1)y + 5 = \frac{1}{4}(x - 1)

Step 1: Rearrange the equation into slope-intercept form y=mx+by = mx + b.

Start by isolating yy:

y=14(x1)5y = \frac{1}{4}(x - 1) - 5

Simplify the equation:

y=14x145y = \frac{1}{4}x - \frac{1}{4} - 5

y=14x14204y = \frac{1}{4}x - \frac{1}{4} - \frac{20}{4}

y=14x214y = \frac{1}{4}x - \frac{21}{4}

Now we have the equation:

y=14x214y = \frac{1}{4}x - \frac{21}{4}

This is in slope-intercept form where:

  • Slope (m) = 1/4
  • y-intercept (b) = -21/4 or -5.25

Graphing Steps:

  1. Start at the y-intercept (21/4 or 5.25)(-21/4 \text{ or } -5.25), which is just below 5-5 on the y-axis.
  2. From this point, use the slope 14\frac{1}{4}, which means for every 4 units you move horizontally to the right (positive x-direction), move 1 unit up.
