Question

Determine if parallel, perpendicular, or neither showing how to find the slope

4x-7y=10
7x+4y=1

Answer 1

Check if they’re product if slope is equal to -1 if yes then it’s perpendicular
And if slopes are equal then parallel...

Answer 2

They're perpendicular

Explanation:

Cause they interfere the point (47/65, 66/65) in a 90 degree angle
