Math Problem Statement

Write the equation in slope-intercept form. Then find the slope and y-intercept of the line: 5x + 2y = 11.

Solution

The given equation is:

5x+2y=115x + 2y = 11

Step 1: Convert the equation to slope-intercept form ( y=mx+by = mx + b )

Start by isolating yy:

2y=5x+112y = -5x + 11

Now, divide by 2:

y=52x+112y = -\frac{5}{2}x + \frac{11}{2}

Step 2: Identify the slope and y-intercept

The slope-intercept form is y=mx+by = mx + b, where mm is the slope and bb is the y-intercept.

From the equation y=52x+112y = -\frac{5}{2}x + \frac{11}{2}:

  • Slope (m) = 52-\frac{5}{2}
  • Y-intercept (b) = 112\frac{11}{2}

Final Answer:

The equation in slope-intercept form is:

y=52x+112y = -\frac{5}{2}x + \frac{11}{2}
