Answer:

Step-by-step explanation:
<u>Equation of a Line</u>
Two variables x and y are linearly dependent when they are related by the equation

where m is the slope and b is the y-intercept, or the value of y when x equals 0. We are given a particular equation for the line such as b=0, so we only need one point to compute m. That point is (-1,-2):

It follows that

Thus the equation of the line is

<em><u>Determine which pattern grows faster from a graph</u></em> by finding the steeper line.
Answer:
elimination
Step-by-step explanation:
You need to eliminate numbers from the equation until it is solved.
