Answer

To graph the equation \( 6x - 2y + 6 = 0 \), find the x-intercept at (–1, 0) and the y-intercept at (0, 3). Plot these points and draw a straight line through them.

Solution

We start with the equation:   6x – 2y + 6 = 0 Step 1. Find the x-intercept (where y = 0):   Substitute y = 0:   6x – 2(0) + 6 = 0  ⟹ 6x + 6 = 0   Subtract 6 from both sides:   6x = –6   Divide by 6:   x = –1   So the x-intercept is (–1, 0). Step 2. Find the y-intercept (where x = 0):   Substitute x = 0:   6(0) – 2y + 6 = 0  ⟹ –2y + 6 = 0   Subtract 6 from both sides:   –2y = –6   Divide by –2:   y = 3   So the y-intercept is (0, 3). Step 3. Graph the line:   Plot the points (–1, 0) and (0, 3) on the coordinate plane. Draw a straight line through these two points. This is the graph of the line defined by the equation 6x – 2y + 6 = 0.

To find the intercepts for the equation \( 6x - 2y + 6 = 0 \), we first convert it to slope-intercept form \( y = mx + b \). Rearranging gives us \( 2y = 6x + 6 \), which simplifies to \( y = 3x + 3 \). Now, to find the intercepts: 1. **Y-Intercept:** Set \( x = 0 \): \( y = 3(0) + 3 = 3 \). So, the y-intercept is \( (0, 3) \). 2. **X-Intercept:** Set \( y = 0 \): \( 0 = 3x + 3 \) leads to \( 3x = -3 \) or \( x = -1 \). So, the x-intercept is \( (-1, 0) \). With the intercepts \( (0, 3) \) and \( (-1, 0) \), you can plot these points on the graph and draw a line through them, extending it in both directions! For your graphing tool, simply input the equation \( 6x - 2y + 6 = 0 \) or plot the points directly. Enjoy sketching your line!
