I can't be entirely sure what you want to "do" about the slope,
but here is how to FIND it if you have the line on the graph:
-- You pick two points on the graph line.
-- Find the difference in 'y' between the two points.
-- Find the difference in 'x' between the two points.
-- The slope of the line between the two points is
(the difference in 'y')
divided by
(the difference in 'x') .
-- If the line on the graph is a straight line, then
the slope is the same everywhere on it.
A quadratic equation is an equation whose leading coefficient is of the second degree. The factored form of the quadratic equation x²-x-2 is (x+1)(x-2).
<h3>What is a quadratic equation?</h3>
A quadratic equation is an equation whose leading coefficient is of second degree also the equation has only one unknown while it has 3 unknown numbers.
It is written in the form of ax²+bx+c.
The factored form of the quadratic equation can be done in the following manner,

Thus, the factored form of the quadratic equation x²-x-2 is (x+1)(x-2).

Answer:
6 hours
Step-by-step explanation:
she played game 25% of the time.
25% of 30 hours is 7.5 hours
she researched 5% of the time.
5% of 30 hours is 1.5 hours
so she played game 7.5-1.5=6 more hours than she researched
