Math Problem Statement

Convert each equation from standard form to slope-intercept form. Example equations: 4x + 6y = 48, 3x - 5y = 25.

Solution

Let's solve the equations step by step to convert them from standard form Ax+By=CAx + By = C to slope-intercept form y=mx+by = mx + b, where mm is the slope and bb is the y-intercept.


1. 4x+6y=484x + 6y = 48

Steps:

  1. Subtract 4x4x from both sides: 6y=4x+486y = -4x + 48
  2. Divide every term by 66 to solve for yy: y=46x+486y = -\frac{4}{6}x + \frac{48}{6}
  3. Simplify fractions: y=23x+8y = -\frac{2}{3}x + 8

Answer: y=23x+8y = -\frac{2}{3}x + 8


2. 3x5y=253x - 5y = 25

Steps:

  1. Subtract 3x3x from both sides: 5y=3x+25-5y = -3x + 25
  2. Divide every term by 5-5 to solve for yy: y=35x+255y = \frac{-3}{-5}x + \frac{25}{-5}
  3. Simplify fractions: y=35x5y = \frac{3}{5}x - 5

Answer: y=35x5y = \frac{3}{5}x - 5
