Math Problem Statement

Find the slope and y-intercept for the equation 4x - 3y = -3 and graph the line.

Solution

Let's solve the given equation of the line, 4x3y=34x - 3y = -3, to find the slope and y-intercept.

We start by converting the equation to slope-intercept form, which is y=mx+by = mx + b, where mm is the slope and bb is the y-intercept.

Step 1: Solve for yy

We have: 4x3y=34x - 3y = -3 Subtract 4x4x from both sides: 3y=4x3-3y = -4x - 3 Now, divide both sides by 3-3: y=43x+1y = \frac{4}{3}x + 1

Step 2: Identify the slope and y-intercept

  • The slope m=43m = \frac{4}{3}
  • The y-intercept b=1b = 1

Now that we have the slope and y-intercept, you can use these values to graph the line on the provided graph.
