Answer:
Steve has a total of $140.
Step-by-step explanation:
At first, we know that Steve has $140.50. Next, he loaned $50 to a friend. This tells us that this money went out of his account.
140.50 - 50 = $90.50
So now, Steve has only $90.50 left.
Then, he spent $31.25. This also tells us that his went out of his account, so we must subtract it.
90.50 - 31.25 = $59.25
Now, Steve has $59.25 left.
Finally, Steve received an $80.75 paycheck from work. This tells us that this money went in to his account.
59.25 + 80.75 = $140
Therefore, Steve now has a total of $140.

Step-by-step explanation:
the slope of a line is always the factor of x in the equation. in our case here : 5/8.
the slope is the y/x ratio indicating how many units y changes, when x changes by a certain amount of units (e.g. when going from one point on the line to another).
the perpendicular slope (crosses the original line in a right angle = 90 degrees) turns x and y upside-down and flips the sign.
so, in our case, it is -8/5.
