9. What is the slope of a line perpendicular to 8x - 6y = -30 in simplest form? (SHOW WORK)

Answer; -3/4
Explanation;

y = mx + b is the slope intercept form of a line where m is the slope and b is the y intercept

For a line in the form of y = mx + b , the slope is m and y intercept is b

M perpendicular = -3/4

The first one, i believe, would be correct. all the others have one thing in common, and that's that they have repeating numbers. in the second one, x and y have repeating 6's and 3's, and in the third, x and y have repeating 6's as well. in the last one, there are repeating 3's. the first one has no repeating numbers.
