Answer:
3
Step-by-step explanation:
The slope is found by
m = (y2-y1)/(x2-x1)
= ( 10-7)/(2-1)
= 3/1
Answer:
The Y intercept would be 1. The slope would be 2.
Step-by-step explanation:
The Y intercept is where a line intercepts, or crosses the Y axis. As you can see in the graph, the line crosses the Y axis at point 1.
To find slope here, you can do the rise divided by the run.
To find this, choose two points. We can use point (0, 1) and point (1, 3)
Next, find the rise, or the vertical distance between the two points. In this case, it would be 2.
Then, find the run, or the horizontal distance between the two points. In this case, it would be 1.
Finally, divide the rise by the run, and create the fraction rise over run, or in this case 2/1.
It is rather obvious that we will have to deal with a trigonometric function. Let us see... the first hint is that a function is not defined somewhere. cos and sin are defined for all real numbers... what about tan though? Well, as we approach pi/2, tan becomes larger and larger and it is not defined at pi/2. Given that the tan function has a period of pi (cos and sin have a period of 2pi), this function is the right candidate. Since it is periodic and it is not defined at pi/2, it cannot be defined at any x=pi/2+-npi (if it was defined for some n, then it would have the same value at pi/2 due to periodicity). Hence, a function that works is tanx, or 2*tanx or tanx+6.
