Explanation:

This is a self-answering question: you solve it by graphing the equations.

<em>The solution is where the lines intersect</em>. The point of intersection of the lines is the point that satisfies all the equations for the lines, hence is a solution to the system. If they do not intersect, there are no solutions. If the lines are coincident, there are an infinite number of solutions.

__

The equations can be graphed by any of a number of methods. (My favorite is to let a graphing calculator do it.) The method of choice depends on the coefficients and the form the equations are given in. Methods of graphing are a topic for a more lengthy discussion.

How long did it take to reach the bottom of the slope
mafiozo [28]
To solve this we are going to use the kinematic equation for final velocity: V_{f}=V_{i}+at
where
V_{f} is the final velocity
V_{i} is the initial velocity 
a is the acceleration 
t is the time

We know for our problem that the the velocity at the beginning of the slope is  2.0ms^{-1}, so V_{i}=2.0. We also know that the speed ad the bottom of the slope is 20ms^{-1}, so V_{f}=20. We also know that the acceleration is 6ms^{-2}, so a=6. Lets replace those values in our formula and solve for t:
V_{f}=V_{i}+at
20=2+6t
6t=18
t= \frac{18}{3}
t=3 seconds

We can conclude that it takes the roller coaster 3 seconds to reach the bottom of the slope.

Does anyone know the answer ?

Y = 3x - 8
Because y = mx + b, where m is the slope and b is the y-intercept, just substitute the two numbers.
