Q. Determine whether the lines are parallel, perpendicular or neither.y=43x+28x+6y=12Parallel perpendicular neither
Find Slope First Line: To determine the relationship between the two lines, we need to find their slopes. If the slopes are equal, the lines are parallel. If the product of the slopes is −1, the lines are perpendicular. Otherwise, they are neither parallel nor perpendicular.
Find Slope Second Line: First, let's find the slope of the first line given by y=43x+2. The slope-intercept form of a line is y=mx+b, where m is the slope. Here, the slope m is clearly 43.
Determine Relationship: Now, let's find the slope of the second line given by 8x+6y=12. We need to rearrange this equation into slope-intercept form, y=mx+b. Let's solve for y.
Isolate y Term: Subtract 8x from both sides of the equation 8x+6y=12 to isolate the y term on one side:6y=−8x+12
Solve for y: Now, divide both sides of the equation by 6 to solve for y: y=6−8x+612
Simplify Fractions: Simplify the fractions:y=3−4x+2The slope of the second line is −34.
Check Parallel Lines: Now we have the slopes of both lines: the first line has a slope of 43, and the second line has a slope of −34. Since these slopes are not equal, the lines are not parallel. To check if they are perpendicular, we multiply the slopes and see if the product is −1.
