Answer:
The slope of the line is 2
Step-by-step explanation:
In this problem you need to know rise over run. This means the slope goes up two and the over one. This makes the slope 2.
When solving a system of equations by graphing it, and there is no intersection between the lines, then it has no solutions.
You have to jusitfy the step that leads from sin (x) = a/c and cos(x) = b/c to sin^2 (x) + cos^2(x) = [a^2 / c^2] + [b^2 / c^2].
As you can see go from the first statement to the second by substituting the value of sin(x) by a/x and the value of cos(x) by b/c.
Then, the answer is the option b. substitution property of equality.
